7.1-0.8x=4.7
Swap sides so that all variable terms are on the left hand side.
-0.8x=4.7-7.1
Subtract 7.1 from both sides.
-0.8x=-2.4
Subtract 7.1 from 4.7 to get -2.4.
x=\frac{-2.4}{-0.8}
Divide both sides by -0.8.
x=\frac{-24}{-8}
Expand \frac{-2.4}{-0.8} by multiplying both numerator and the denominator by 10.
x=3
Divide -24 by -8 to get 3.
