Question

4m-3n=8; solve for m

Answer 1

move all terms that don't contain m to the right side and solve.
m=3n/4 +2

Answer 2

4m - 3n = 8

Add 3n to both sides.

4m = 3n + 8

Divide both sides by 4.

m = 3/4n + 2

So, m = 3/4n + 2

However, if you made a typo, and meant 3m instead of 3n, your answer would be :

4m - 3n = 8

n = 8
