6.4+0.36x-x=3.2
Subtract x from both sides.
6.4-0.64x=3.2
Combine 0.36x and -x to get -0.64x.
-0.64x=3.2-6.4
Subtract 6.4 from both sides.
-0.64x=-3.2
Subtract 6.4 from 3.2 to get -3.2.
x=\frac{-3.2}{-0.64}
Divide both sides by -0.64.
x=\frac{-320}{-64}
Expand \frac{-3.2}{-0.64} by multiplying both numerator and the denominator by 100.
x=5
Divide -320 by -64 to get 5.
