blank 1:

Explanation:

Step1: Combine like terms

First, combine the \( m \)-terms and the constant terms on the right side. For the \( m \)-terms: \( -6m + 3m = -3m \). For the constant terms: \( -4 - 8 = -12 \). So the equation becomes \( 18 = -3m - 12 \).

Step2: Add 12 to both sides

To isolate the term with \( m \), add 12 to both sides of the equation. \( 18 + 12 = -3m - 12 + 12 \), which simplifies to \( 30 = -3m \).

Step3: Divide by -3

Now, divide both sides by -3 to solve for \( m \). \( \frac{30}{-3} = \frac{-3m}{-3} \), so \( m = -10 \).

Answer:

-10
