Solution for 2.5(m-0.4)-0.5m=2-0.5(m+4) equation:


Simplifying
2.5(m + -0.4) + -0.5m = 2 + -0.5(m + 4)

Reorder the terms:
2.5(-0.4 + m) + -0.5m = 2 + -0.5(m + 4)
(-0.4 * 2.5 + m * 2.5) + -0.5m = 2 + -0.5(m + 4)
(-1 + 2.5m) + -0.5m = 2 + -0.5(m + 4)

Combine like terms: 2.5m + -0.5m = 2m
-1 + 2m = 2 + -0.5(m + 4)

Reorder the terms:
-1 + 2m = 2 + -0.5(4 + m)
-1 + 2m = 2 + (4 * -0.5 + m * -0.5)
-1 + 2m = 2 + (-2 + -0.5m)

Combine like terms: 2 + -2 = 0
-1 + 2m = 0 + -0.5m
-1 + 2m = -0.5m
