13
m+m when m equals 2. 2+2 4
11m + 13 = m + 23 10m + 13 = 23 10m = 10 m = 1
6 + m = 16 m = 16 - 6 = 10
6
-2
m + 9 = 2 Therefore, m = 2 - 9 m = -7
22m Think of the "m" as a "monkey". 2 monkeys + 2 monkeys + 9 monkeys + 9 monkeys = 22 monkeys
m = 15
15-2 = 13
M= 2.
2m + 2 = 3m + 4 => 2m-3m = 4-2 => -m = 2 => m= -2
