15x-20x=-60-12x
Multiply both sides of the equation by 60, the least common multiple of 4,3,5.
-5x=-60-12x
Combine 15x and -20x to get -5x.
-5x+12x=-60
Add 12x to both sides.
7x=-60
Combine -5x and 12x to get 7x.
x=\frac{-60}{7}
Divide both sides by 7.
x=-\frac{60}{7}
Fraction \frac{-60}{7} can be rewritten as -\frac{60}{7} by extracting the negative sign.
