1.2m-0.8+2m=0
Add 2m to both sides.
3.2m-0.8=0
Combine 1.2m and 2m to get 3.2m.
3.2m=0.8
Add 0.8 to both sides. Anything plus zero gives itself.
m=\frac{0.8}{3.2}
Divide both sides by 3.2.
m=\frac{8}{32}
Expand \frac{0.8}{3.2} by multiplying both numerator and the denominator by 10.
m=\frac{1}{4}
Reduce the fraction \frac{8}{32} to lowest terms by extracting and canceling out 8.
