Answer 2

To solve the equation $12 - (4x + 5) = 7 + x$, we'll follow these steps:

1. Distribute the negative sign inside the parentheses: $12 - 4x - 5 = 7 + x$

2. Combine like terms on both sides of the equation: $7 - 4x = 7 + x$

3. Move all terms involving $x$ to one side of the equation: $7 - 7 = x + 4x$ $0 = 5x$

4. Solve for $x$: $x = 0$
