Solution for 3m-2n=0.4(8m+3n) equation:


Simplifying
3m + -2n = 0.4(8m + 3n)
3m + -2n = (8m * 0.4 + 3n * 0.4)
3m + -2n = (3.2m + 1.2n)

Solving
3m + -2n = 3.2m + 1.2n

Solving for variable 'm'.

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

Add '-3.2m' to each side of the equation.
3m + -3.2m + -2n = 3.2m + -3.2m + 1.2n

Combine like terms: 3m + -3.2m = -0.2m
-0.2m + -2n = 3.2m + -3.2m + 1.2n

Combine like terms: 3.2m + -3.2m = 0.0
-0.2m + -2n = 0.0 + 1.2n
-0.2m + -2n = 1.2n

Add '2n' to each side of the equation.
-0.2m + -2n + 2n = 1.2n + 2n

Combine like terms: -2n + 2n = 0
-0.2m + 0 = 1.2n + 2n
-0.2m = 1.2n + 2n

Combine like terms: 1.2n + 2n = 3.2n
-0.2m = 3.2n

Divide each side by '-0.2'.
m = -16n

Simplifying
m = -16n
