30+0.13x-0.15x=0
Subtract 0.15x from both sides.
30-0.02x=0
Combine 0.13x and -0.15x to get -0.02x.
-0.02x=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-30}{-0.02}
Divide both sides by -0.02.
x=\frac{-3000}{-2}
Expand \frac{-30}{-0.02} by multiplying both numerator and the denominator by 100.
x=1500
Divide -3000 by -2 to get 1500.
