Subtract 0.8 m from both sides of the equation.
1.2m3.20.8m=0.8m1.60.8m
Combine the like terms.
(1.2m0.8m)3.2=(0.8m0.8m)1.6
0.4m3.2=01.6
0.4m3.2=1.6
Again, add 3.2 to both sides of the equation.
0.4m3.2+3.2=1.6+3.2
Combine the like terms.
0.4m0=1.6+3.2
0.4 m=1.6
Express rhe decimal linear equation as an equivalent linear equation without decimals.
Multiply both sides of the equation by 10.
10(0.4m)=10(1.6)
4 m=16
Divide both sides of the equation by 4.
4m4=164
m=4
Check the solution by substituting m=4 in the original equation.
1.2(4)3.2(=)0.8(4)1.6
4.83.2=3.21.6v
1.6=1.6
Since m=4 satisfiesnthe original equation, the solution is 4.
