2m + 2 = 3m + 4
=> 2m-3m = 4-2
=> -m = 2
=> m= -2

-2m + 7 = m - 2 +7 +2 = m +2m 9 = 3m 3m = 9 m = 9/3 = 3 to test: -2(3) + 7 = (3) - 2 -6 + 7 = 3 - 2 1 = 1
-3m + 8 = 2 -3m = 2 - 8 -3m = -6 m = -6/-3 m = 2
5m+3=3m+9 First get the ms and the constants on separate sides. Do this by subtracting 3 from both sides (5m=3m+6) Then subtract 3m from both sides (2m=6) then divide both sides by 2 to find m. (m=3)
M= 2.
