x + 7 + 3(4 + 5) = (x * 12) + 12

I came to up with the answer of 35 but that answer isn't sitting well with me not sure where I went wrong can anyone help?!!!

x + 7 + 3(4 + 5) = (x * 12) + 12

x + 7 + 12 + 15 = 12x + 12

22 = 11x

? = x

Thank you once again Sue life saver Amilia not sure if your question was directed towards me but I'm lost on that question right now.

You're welcome.

I'll remove emilia's post. It is confusing when someone piggy backs a question on another person's post.

not a problem I was confused I thought it may have been something like that. Thanks again :)

To solve the equation x + 7 + 3(4 + 5) = (x * 12) + 12, you need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, and Addition and Subtraction - from left to right).

Let's break down the equation step by step:

1. Simplify the expression within parentheses: 4 + 5 = 9.
Now the equation becomes: x + 7 + 3(9) = (x * 12) + 12.

2. Perform the multiplication: 3 * 9 = 27.
The equation becomes: x + 7 + 27 = (x * 12) + 12.

3. Simplify both sides of the equation by combining like terms:
On the left side: x + 7 + 27 becomes x + 34.
On the right side: (x * 12) + 12 remains the same.

The equation is now: x + 34 = (x * 12) + 12.

4. Next, isolate the variable terms and constants on separate sides of the equation.
Subtract x from both sides:
x + 34 - x = (x * 12) + 12 - x.

The x term cancels out, and we have:
34 = (x * 12) + 12 - x.

5. Combine like terms on the right side:
34 = 12x + 12 - x.

6. Simplify the expression:
Combine the x terms: 12x - x = 11x.
Combine the constant terms: 12 + 12 = 24.

The equation becomes: 34 = 11x + 24.

7. To solve for x, isolate the variable term:
Subtract 24 from both sides:
34 - 24 = 11x + 24 - 24.

Simplifying further:
10 = 11x.

8. Finally, solve for x by dividing both sides by 11:
x = 10/11.

Therefore, the solution to the equation x + 7 + 3(4 + 5) = (x * 12) + 12 is x = 10/11, not 35.
