92-x=0.15x
Multiply 115 and 0.8 to get 92.
92-x-0.15x=0
Subtract 0.15x from both sides.
92-1.15x=0
Combine -x and -0.15x to get -1.15x.
-1.15x=-92
Subtract 92 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-92}{-1.15}
Divide both sides by -1.15.
x=\frac{-9200}{-115}
Expand \frac{-92}{-1.15} by multiplying both numerator and the denominator by 100.
x=80
Divide -9200 by -115 to get 80.
