\frac{13}{15}x+4-x=0
Subtract x from both sides.
-\frac{2}{15}x+4=0
Combine \frac{13}{15}x and -x to get -\frac{2}{15}x.
-\frac{2}{15}x=-4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
x=-4\left(-\frac{15}{2}\right)
Multiply both sides by -\frac{15}{2}, the reciprocal of -\frac{2}{15}.
x=\frac{-4\left(-15\right)}{2}
Express -4\left(-\frac{15}{2}\right) as a single fraction.
x=\frac{60}{2}
Multiply -4 and -15 to get 60.
x=30
Divide 60 by 2 to get 30.
