Answer
x=18
Work Step by Step
$\frac{x}{2}+\frac{x}{3}-15=0$ convert the fractions to the least common denominator of 6; add 15 to both sides
$\frac{3x}{6}+\frac{2x}{6}-15+15=0+15$ simplify
$\frac{5x}{6}=15$ multiply both sides by 6
$\frac{5x}{6}\times6=15\times6$ simplify
$5x=90$ divide both sides by 5
$5x\div5=90\div5$ simplify
$x=18$
