3.1x-0.5-2.72x=0.64
Subtract 2.72x from both sides.
0.38x-0.5=0.64
Combine 3.1x and -2.72x to get 0.38x.
0.38x=0.64+0.5
Add 0.5 to both sides.
0.38x=1.14
Add 0.64 and 0.5 to get 1.14.
x=\frac{1.14}{0.38}
Divide both sides by 0.38.
x=\frac{114}{38}
Expand \frac{1.14}{0.38} by multiplying both numerator and the denominator by 100.
x=3
Divide 114 by 38 to get 3.
