0.1x+2.51-0.02x=2.11
Subtract 0.02x from both sides.
0.08x+2.51=2.11
Combine 0.1x and -0.02x to get 0.08x.
0.08x=2.11-2.51
Subtract 2.51 from both sides.
0.08x=-0.4
Subtract 2.51 from 2.11 to get -0.4.
x=\frac{-0.4}{0.08}
Divide both sides by 0.08.
x=\frac{-40}{8}
Expand \frac{-0.4}{0.08} by multiplying both numerator and the denominator by 100.
x=-5
Divide -40 by 8 to get -5.
