2x+3.6=4
Multiply 3 and 1.2 to get 3.6.
2x=4-3.6
Subtract 3.6 from both sides.
2x=0.4
Subtract 3.6 from 4 to get 0.4.
x=\frac{0.4}{2}
Divide both sides by 2.
x=\frac{4}{20}
Expand \frac{0.4}{2} by multiplying both numerator and the denominator by 10.
x=\frac{1}{5}
Reduce the fraction \frac{4}{20} to lowest terms by extracting and canceling out 4.
