20.4+3.2x=1.8
Multiply 3 and 6.8 to get 20.4.
3.2x=1.8-20.4
Subtract 20.4 from both sides.
3.2x=-18.6
Subtract 20.4 from 1.8 to get -18.6.
x=\frac{-18.6}{3.2}
Divide both sides by 3.2.
x=\frac{-186}{32}
Expand \frac{-18.6}{3.2} by multiplying both numerator and the denominator by 10.
x=-\frac{93}{16}
Reduce the fraction \frac{-186}{32} to lowest terms by extracting and canceling out 2.
