0.5x-6-0.2x=0
Subtract 0.2x from both sides.
0.3x-6=0
Combine 0.5x and -0.2x to get 0.3x.
0.3x=6
Add 6 to both sides. Anything plus zero gives itself.
x=\frac{6}{0.3}
Divide both sides by 0.3.
x=\frac{60}{3}
Expand \frac{6}{0.3} by multiplying both numerator and the denominator by 10.
x=20
Divide 60 by 3 to get 20.
