All of the following equations have the same solution except
3 m + 2 = -10
2 - 3 m = -10
-10 = -3 m + 2
-3 m + 2 = -10

3m+2=-10m=-4
2-3m=-10m=4
-10=-3m+2m=4
-3m+2=-10m=4
so the answer is (a)

3m=-10-2 3m=-12 m=-4
2 will be negative when it comes to right side,if we had -2it became 2 after changing its place to right side

-3m=-2-10 -3m=-12 m=4
-10-2=-3m -12=-3m m=4
-3m=-2-10 -3m=-12 m=4

3m + 2 = -10      2 - 3m = -10          -10 = -3m + 2               -3m + 2 = -10
m = -4                      m = 4                    m = 4                           m = 4
