2SHIRTS + 3 SHORTS=88.15
3SHIRTS + 1 SHORTS=66.60 THEREFORE 1 SHORTS =66.60-3 SHIRTS SUBSTITUTING FOR SHORTS IN EQUATION 1 WE GET
2 SHIRTS + 3(66.60-3 SHIRTS)=66.60 OR 2 SHIRTS + 199.80-9 SHIRTS=66.60 OR
2 SHIRTS -9 SHIRTS=66.60-199.80 OR -7 SHIRTS=-111.65 OR 1 SHIRT =-111.65/-7 OR
SHIRTS=15.95 EACH THEREFORE
2(15.95)+3 SHORTS=88.15 OR 31.90 +3 SHORTS=88.15 OR 3 SHORTS =88.15-31.90 OR
SHORTS=56.25/3 OR SHORTS =18.75 EACH.
