38000=0.8x
Combine x and -0.2x to get 0.8x.
0.8x=38000
Swap sides so that all variable terms are on the left hand side.
x=\frac{38000}{0.8}
Divide both sides by 0.8.
x=\frac{380000}{8}
Expand \frac{38000}{0.8} by multiplying both numerator and the denominator by 10.
x=47500
Divide 380000 by 8 to get 47500.
