2x+24-12x=-4
Subtract 12x from both sides.
-10x+24=-4
Combine 2x and -12x to get -10x.
-10x=-4-24
Subtract 24 from both sides.
-10x=-28
Subtract 24 from -4 to get -28.
x=\frac{-28}{-10}
Divide both sides by -10.
x=\frac{14}{5}
Reduce the fraction \frac{-28}{-10} to lowest terms by extracting and canceling out -2.
