Answer:

11m

Explanation:

9m + 3m - m = ?

just look at it without the variables: m

9 + 3 - 1 = ?

The reason there is a 1 before the m is because there is always atleast a 1 before a variable. 1 x m = m, but 0 x m = 0. so '1'.

ok so now lets solve

9 + 3 - 1

12 - 1

11

so the answer is 11, add the variables back

9m + 3m - m

12m - m

11m
