Question

1. 5(x + 3) - 5 = 20

Explanation:

Step1: Add 5 to both sides

$5(x + 3) - 5 + 5 = 20 + 5$
Simplifies to: $5(x + 3) = 25$

Step2: Divide both sides by 5

$\frac{5(x + 3)}{5} = \frac{25}{5}$
Simplifies to: $x + 3 = 5$

Step3: Subtract 3 from both sides

$x + 3 - 3 = 5 - 3$
Simplifies to: $x = 2$

Answer:

$x = 2$
