54+0.09x-0.13x=38
Subtract 0.13x from both sides.
54-0.04x=38
Combine 0.09x and -0.13x to get -0.04x.
-0.04x=38-54
Subtract 54 from both sides.
-0.04x=-16
Subtract 54 from 38 to get -16.
x=\frac{-16}{-0.04}
Divide both sides by -0.04.
x=\frac{-1600}{-4}
Expand \frac{-16}{-0.04} by multiplying both numerator and the denominator by 100.
x=400
Divide -1600 by -4 to get 400.
