Answer 3

Sure, I'd be happy to help you solve the equation!

The equation you provided is:

(x + 27) - 12 = 42

To solve for x, follow these steps:

Step 1: Simplify the equation. (x + 27) - 12 = 42 Combine like terms within the parentheses: x + 15 = 42

Step 2: Isolate the variable x on one side of the equation. To do this, you need to get rid of the constant term on the left side. Since the constant term is +15, you can eliminate it by subtracting 15 from both sides of the equation: x + 15 - 15 = 42 - 15 x = 27

Step 3: Verify your solution. To check if the solution is correct, substitute the value of x (which is 27) back into the original equation: (27 + 27) - 12 = 42 54 - 12 = 42 42 = 42

The equation is true, so the solution is correct. Therefore, x = 27.
