22m Think of the "m" as a "monkey". 2 monkeys + 2 monkeys + 9 monkeys + 9 monkeys = 22 monkeys
27
m+m when m equals 2. 2+2 4
3*9 + 2 and that would be 27 + 2 which, in turn is 29.
m = 20/9 or 2 and 2/9
m = 31m + 9 = 1(3) + 9 = 3 + 9 = 12
the answer to that is 5
-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
2 - 3m + 7 = 4m - 9 - m - 28 46 = 6m 46/6 = 23/3 = 7.6666 = m
