m = - 5
Step-by-step explanation:
Simplify both sides of the equation.
4 (m-2) = 2 (m-9)
(4) (m) + (4) (-2) = (2) (m) + (2) (-9) (Distribute)
4m+-8=2m+-18
4m-8=2m-18
Subtract 2m from both sides.
4m-8-2m=2m-18-2m
2m-8=-18
Add 8 to both sides.
2m-8+8=-18+8
2m=-10
Divide both sides by 2.
2m/2 = - 10/2
m = - 5
