4.
x = [?]

Answer 1

Answer:

x = 1

Step-by-step explanation:

$\frac{3x-3}{5}$ = $\frac{2x-2}{4}$ ( cross- multiply )

4(3x - 3) = 5(2x - 2) ← distribute parenthesis on both sides

12x - 12 = 10x - 10 ( subtract 10x from both sides )

2x - 12 = - 10 ( add 12 to both sides )

2x = 2 ( divide both sides by 2 )

x = 1
