12x+15=20x
Multiply both sides of the equation by 5.
12x+15-20x=0
Subtract 20x from both sides.
-8x+15=0
Combine 12x and -20x to get -8x.
-8x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-8}
Divide both sides by -8.
x=\frac{15}{8}
Fraction \frac{-15}{-8} can be simplified to \frac{15}{8} by removing the negative sign from both the numerator and the denominator.
