Solution for 4(0.2m-0.3n)-6(0.7m-0.5n)=0 equation:


Simplifying
4(0.2m + -0.3n) + -6(0.7m + -0.5n) = 0
(0.2m * 4 + -0.3n * 4) + -6(0.7m + -0.5n) = 0
(0.8m + -1.2n) + -6(0.7m + -0.5n) = 0
0.8m + -1.2n + (0.7m * -6 + -0.5n * -6) = 0
0.8m + -1.2n + (-4.2m + 3n) = 0

Reorder the terms:
0.8m + -4.2m + -1.2n + 3n = 0

Combine like terms: 0.8m + -4.2m = -3.4m
-3.4m + -1.2n + 3n = 0

Combine like terms: -1.2n + 3n = 1.8n
-3.4m + 1.8n = 0

Solving
-3.4m + 1.8n = 0

Solving for variable 'm'.

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