Wendy has 5 pairs of pants and 8 shirts. How many different combinations could she form with these items?
Multiply the number of choices for each item to find out the number of combinations (5 × 8 = 40). There are 40 combinations.
Solve for x , y (x + y - 8)/2 =( x + 2 y - 14)/3 = (3 x + y - 12 )/ 11 (Ans: x=2, y=6) Ans : x+ y - 8/2 = x + 2y - 14 /3 = 3x+ y- 12/11
2yx+3y=30
