15-2x=0
Multiply both sides of the equation by 10, the least common multiple of 2,5.
-2x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-2}
Divide both sides by -2.
x=\frac{15}{2}
Fraction \frac{-15}{-2} can be simplified to \frac{15}{2} by removing the negative sign from both the numerator and the denominator.
