Solve: 1/5 (10x-15) = 1/4 (12x-8)

1/5 (10x-15) = 1/4 (12x-8)

1/5 (10x-15) = 1/4 (12x-8)

Simplify:

(1/5) (10x) + (15) (-15) = (1/4) (12x) + (1/4) (-8) (Distribute)

2x+-3=3x+-2

2x-3=3x-2

Subtract 3x from both sides.

2x-3-3x=3x-2-3x

-x-3=-2

Add 3 to both sides.

-x-3+3=-2+3

-x=1

Divide both sides by - 1.

-x/-1 = 1/-1

x=-1
