Question

1. solve each equation.

a) 4x = -28

Explanation:

Step1: Divide both sides by 4

To solve for \( x \), we divide both sides of the equation \( 4x = -28 \) by 4. This is because we want to isolate \( x \), and since \( x \) is multiplied by 4, dividing by 4 will reverse that operation.

$$ \frac{4x}{4} = \frac{-28}{4} $$

Step2: Simplify both sides

Simplifying the left side, \( \frac{4x}{4} = x \). Simplifying the right side, \( \frac{-28}{4} = -7 \).

Answer:

\( x = -7 \)
