How do I solve a problem like this?

m - 4 = 2m

m = -4
m -4=2m -4+m=2m (reorder) -4 + 1m + -2m = 2m + -2m (added -2m to both sides) -4+ -1m =0 (added like terms) -4 +4+ -1m = 0+4 (added 4 to each side) -1m = 4 m=-4 (divided by -1)

To solve the equation m − 4 = 2 m , subtract m from both sides to isolate m , resulting in m = − 4 . You can verify the solution by substituting it back into the original equation.
