Match the equation with the step needed to solve it.
saveliy_v [14]

To Match

To isolate -1 we need to subtract 2m from both sides

2m - 1 = 3m                    (SUBTRACT 2m)

To isolate 1 we need to subtract m from both sides

2m = 1 + m                 (SUBTRACT m)

To isolate m we need to add 1 from both sides

m - 1 = 2                       (ADD 1)

To isolate m we need to subtract 2 from both sides

2 + m = 3                   (SUBTRACT 2)

To isolate m we need to add 2 from both sides

-2 + m = 1                        (ADD 2)

To isolate m we need to subtract 1 from both sides

3 = 1 + m        (SUBTRACT 1)

The steps needed are written in bold.
