If: 9m+2m = 33 Then: m = 3
6
2m + 2 = 3m + 4 => 2m-3m = 4-2 => -m = 2 => m= -2
5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6
5m = 2m - 153m = -15m = -15/3m = -5
M= 2.
m=9
(10, 2)
2m + 5 = 10 Therefore, 2m = 5 m = 5/2 m = 2.5
13=m+2m=11
2m - 9 = 12→ 2m - 9 + 9 = 12 + 9→ 2m = 21→ 2m ÷ 2 = 21 ÷ 2→ m = 101/2 = 10.52m - 9 = 12Add 9 to each side of the equation:2m = 21Divide each side by 2 :m = 10.5
2m+7-m=-402m-m+7=-40m+7=-40m=-47
