x-0.4-0.2x=6
Subtract 0.2x from both sides.
0.8x-0.4=6
Combine x and -0.2x to get 0.8x.
0.8x=6+0.4
Add 0.4 to both sides.
0.8x=6.4
Add 6 and 0.4 to get 6.4.
x=\frac{6.4}{0.8}
Divide both sides by 0.8.
x=\frac{64}{8}
Expand \frac{6.4}{0.8} by multiplying both numerator and the denominator by 10.
x=8
Divide 64 by 8 to get 8.
