Solve the equation for m: -3x + 15 = 42

Answer 1

To solve for \( x \) in the equation \(-3x + 15 = 42\), follow these steps:

1. Subtract 15 from both sides:

\[ -3x + 15 - 15 = 42 - 15 \] \[ -3x = 27 \]

2. Divide both sides by -3:

\[ x = \frac{27}{-3} \] \[ x = -9 \]

So, the solution for \( x \) is:

\[ x = -9 \]
