We are given a string "OM". We need to output the code that processes this string.
Since the problem is very minimal, I assume we are to write a program that takes a string and processes it in some way.
However, the problem does not specify what to do. Let me think about common tasks with such a string.
Possibilities:
Reverse the string: "OM" reversed is "MO"
Convert to uppercase or lowercase: "OM" is already uppercase, but if we convert to lowercase we get "om".
Count the characters: 2
Check if it is a palindrome: "OM" reversed is "MO", which is not the same, so false.
Or perhaps we are to output the string as is.
But the problem says "OM" and then we have to output the code. So maybe we are to write a program that outputs "OM"?
However, the instruction is: "output the final answer within your code"
Since the problem is ambiguous, I will provide a simple program that outputs the string "OM".
Let me write a program in Python that prints "OM".
The given string is "OM". Here's a Python program that processes this string by converting it to uppercase (though it's already uppercase) and then reverses it:
# Input string
s = "OM"
# Process: convert to uppercase (redundant here) and reverse
result = s.upper()[::-1]
# Output the result
print(result)
Explanation:
s.upper() converts the string to uppercase (though "OM" is already uppercase).
[::-1] reverses the string, turning "OM" into "MO".
print(result) outputs "MO".
Output:
MO
This code demonstrates basic string manipulation in Python. If you need a different operation (e.g., counting characters, checking palindromes), clarify the requirements!
Okay, so I need to figure out how to solve this problem where I have to find the value of x in the equation 3x + 5 = 20. Let me start by recalling what I know about algebra.
First, the equation is 3x plus 5 equals 20. The goal is to find the value of x that makes this equation true. I remember that to solve for x, I need to isolate it on one side of the equation. That means I have to get rid of the 5 that's being added to the 3x.
So, the first step would be to subtract 5 from both sides of the equation. That way, I keep the equation balanced. Let me write that down:
3x + 5 - 5 = 20 - 5
Simplifying both sides, the +5 and -5 on the left side cancel each other out, leaving just 3x. On the right side, 20 minus 5 is 15. So now the equation is 3x = 15.
Now, I need to get x by itself. Since 3 is multiplied by x, I should do the opposite operation, which is division. So I divide both sides of the equation by 3:
3x / 3 = 15 / 3
That simplifies to x = 5.
Wait, let me check if that's correct. If I plug x = 5 back into the original equation, does it hold true?
Original equation: 3x + 5 = 20
Substituting x with 5: 3*(5) + 5 = 15 + 5 = 20.
Yes, that equals 20, which matches the right side of the equation. So x = 5 is indeed the correct solution.
But just to make sure I didn't make any mistakes in my steps, let me go through them again. Starting with 3x + 5 = 20. Subtract 5 from both sides: 3x = 15. Then divide by 3: x = 5. Yep, that seems right.
I think that's all there is to it. Sometimes I might overcomplicate things, but in this case, it's straightforward. Just two steps: subtract 5 and then divide by 3. No fractions or decimals involved here.
Another way to look at it is to think about what 3x represents. If 3 times some number plus 5 equals 20, then 3 times that number must be 15 because 20 minus 5 is 15. So, 3x = 15 leads to x = 5.
I guess there's not much more to it. Maybe if the numbers were different, there could be more steps, but here it's pretty simple. Just basic algebra principles.
Wait, just to test my understanding, what if the equation was 3x - 5 = 20? Then I would add 5 to both sides first, right? So 3x = 25, then x = 25/3. But in this problem, it's addition, so subtraction is the correct inverse operation.
Also, if there were a coefficient in front of the x that wasn't a whole number, like 2.5x + 5 = 20, then I would still subtract 5 first, getting 2.5x = 15, then divide by 2.5 to get x = 6. But in our case, the coefficient is 3, which is easy to divide.
So, all in all, I think I did it right. The key steps are reversing the operations: first subtracting the constant term, then dividing by the coefficient. It's important to perform the same operation on both sides to maintain the equality.
I don't see any errors in my calculations. The check by substitution works, so x = 5 is definitely the solution. Maybe I can also graph this equation to visualize it. The left side is a linear function y = 3x + 5, and the right side is y = 20. The intersection point would be at x = 5, y = 20. That makes sense.
Alternatively, creating a table of values for x and y = 3x + 5:
x | y
0 | 5
1 | 8
2 | 11
3 | 14
4 | 17
5 | 20
So when x is 5, y is 20, which is exactly the equation given. That confirms it again.
I think I've covered all the ways to verify this. It seems solid. No mistakes detected. The answer is 5.
To solve the equation (3x + 5 = 20) for (x):
Subtract 5 from both sides to isolate the term with (x):
[
3x + 5 - 5 = 20 - 5 \implies 3x = 15
]
Divide both sides by 3 to solve for (x):
[
\frac{3x}{3} = \frac{15}{3} \implies x = 5
]
Verification:
Substitute (x = 5) back into the original equation:
[
3(5) + 5 = 15 + 5 = 20
]
The left side equals the right side, confirming the solution is correct.
Answer: (\boxed{5})
