-15 + 12x = 5x + 7 -3x SOLVE FOR X

Natali [406]

Answer: $x=\frac{11}{5}$

Simplify both sides of the equation

$-15+12x=5x+7+-3x$

$12x-15=(5x+-3x)+(7)$ (Combine Like Terms)

$12x-15=2x+7$

Subtract 2x from both sides

$12x-15-2x=2x+7-2x\\10x-15=7$

Divide both sides by 10

$\frac{10x}{10} =\frac{22}{10}$

$x=\frac{11}{5}$
