Question

1. 3(x - 7) = -18

Explanation:

Step1: Divide both sides by 3

To isolate the term with \( x \), we divide both sides of the equation \( 3(x - 7) = -18 \) by 3. This gives us \( \frac{3(x - 7)}{3} = \frac{-18}{3} \), which simplifies to \( x - 7 = -6 \).

Step2: Add 7 to both sides

To solve for \( x \), we add 7 to both sides of the equation \( x - 7 = -6 \). So, \( x - 7 + 7 = -6 + 7 \), which simplifies to \( x = 1 \).

Answer:

\( x = 1 \)
