Solution for 7(m-1)-4(2m-4)=2m-3m equation:


Simplifying
7(m + -1) + -4(2m + -4) = 2m + -3m

Reorder the terms:
7(-1 + m) + -4(2m + -4) = 2m + -3m
(-1 * 7 + m * 7) + -4(2m + -4) = 2m + -3m
(-7 + 7m) + -4(2m + -4) = 2m + -3m

Reorder the terms:
-7 + 7m + -4(-4 + 2m) = 2m + -3m
-7 + 7m + (-4 * -4 + 2m * -4) = 2m + -3m
-7 + 7m + (16 + -8m) = 2m + -3m

Reorder the terms:
-7 + 16 + 7m + -8m = 2m + -3m

Combine like terms: -7 + 16 = 9
9 + 7m + -8m = 2m + -3m

Combine like terms: 7m + -8m = -1m
9 + -1m = 2m + -3m

Combine like terms: 2m + -3m = -1m
9 + -1m = -1m

Add 'm' to each side of the equation.
