Answer 2

How to solve your question

$5(x - 1)$

solve

$Distribute \\ \\ 5( x - 1) = 15 \\ 5x - 5 = 15$

Add 5 to both sides of the equation

$5x - 5 = 15 \\ 5x - 5 + 5 = 15 + 5$

Simplify

$5x = 20$

Divide both sides of the equation by the same term

$5x = 20 \\ \\ \frac{5x}{5} = \frac{20}{5}$

Simplify

$x = 4$

Solution

$x = 4$
