Question

1. -20 = -5b

Explanation:

Step1: Divide both sides by -5

To solve for \( b \), we divide both sides of the equation \(-20 = -5b\) by \(-5\). The formula for this step is \(\frac{-20}{-5}=\frac{-5b}{-5}\).

Step2: Simplify both sides

Simplifying the left side, \(\frac{-20}{-5} = 4\). Simplifying the right side, \(\frac{-5b}{-5}=b\). So we get \( b = 4 \).

Answer:

\( b = 4 \)
