0.1-2x=0.078
Swap sides so that all variable terms are on the left hand side.
-2x=0.078-0.1
Subtract 0.1 from both sides.
-2x=-0.022
Subtract 0.1 from 0.078 to get -0.022.
x=\frac{-0.022}{-2}
Divide both sides by -2.
x=\frac{-22}{-2000}
Expand \frac{-0.022}{-2} by multiplying both numerator and the denominator by 1000.
x=\frac{11}{1000}
Reduce the fraction \frac{-22}{-2000} to lowest terms by extracting and canceling out -2.
