0.4(m-24)=1.2m

Solution for 0.4(m-24)=1.2m equation:

Simplifying
0.4(m + -24) = 1.2m

Reorder the terms:
0.4(-24 + m) = 1.2m
(-24 * 0.4 + m * 0.4) = 1.2m
(-9.6 + 0.4m) = 1.2m

Solving
-9.6 + 0.4m = 1.2m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-1.2m' to each side of the equation.
-9.6 + 0.4m + -1.2m = 1.2m + -1.2m

Combine like terms: 0.4m + -1.2m = -0.8m
-9.6 + -0.8m = 1.2m + -1.2m

Combine like terms: 1.2m + -1.2m = 0.0
-9.6 + -0.8m = 0.0

Add '9.6' to each side of the equation.
-9.6 + 9.6 + -0.8m = 0.0 + 9.6

Combine like terms: -9.6 + 9.6 = 0.0
0.0 + -0.8m = 0.0 + 9.6
-0.8m = 0.0 + 9.6

Combine like terms: 0.0 + 9.6 = 9.6
-0.8m = 9.6

Divide each side by '-0.8'.
m = -12

Simplifying
m = -12
