factor trees are nice.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
