Question

a clothing store is having on shirts and jeans. four shirts and two pairs of jeans cost $72. Five shirts and three pair of jeans cost $99.

Answer 1

Explanation:

s= shirts

j= jeans

4s + 2j = 72

5s + 3j = 99

10s + 6j = 198

-12s - 6j = -216

-2s = -18

s = $9

4(9) + 2j = 72

36 + 2j = 72

2j = 36

j = $18
