Question

Annette’s soccer team will play 15 games this season. That is 7 games fewer than 2 times the number of games they played last season. How many games did they play last season? Represent this problem with an equation in the form px+q=r
.

Answer 1

Let x = number of games last season. Twice that minus 7 equals 15, so
2x - 7 = 15
(here p = 2, q = -7, r = 15). Solving gives 2x = 22, so x = 11.
