100-0.02x=42
Swap sides so that all variable terms are on the left hand side.
-0.02x=42-100
Subtract 100 from both sides.
-0.02x=-58
Subtract 100 from 42 to get -58.
x=\frac{-58}{-0.02}
Divide both sides by -0.02.
x=\frac{-5800}{-2}
Expand \frac{-58}{-0.02} by multiplying both numerator and the denominator by 100.
x=2900
Divide -5800 by -2 to get 2900.
