Question

Eight shirts and six pairs of pants cost $726. Nine shirts and seven pairs of pants cost $831. Write a system of equations for the problem , using x as the cost of a shirt and y as the cost of a pair of pants.

Answer 1

Explanation:

8x + 6y = 726

9x + 7y = 831

56x + 42y = 5082

-54x - 42y = -4986

2x = 95

x = 47.50 Shirt

47.50(8) + 6y = 726

380 + 6y = 726

6y = 346

y = 57.67 pants
