4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9

3+4m+5m=214m+5m=21-39m=18m=18/9m=2
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
5m = 2m - 153m = -15m = -15/3m = -5

m = 4
m = 8
(10, 2)
simplified it equals, 9m+8
5m - 5 + 2 = 1 Therefore, 5m - 3 = 1 5m = 4 m = 4/5 m = 0.8
