how to solve this problem

Question

elaine brought a tolal of 15 shirts and pairs of pants. she brought 7 more shirts than pants. how many of each did she buy? help please show me how you got your answer.

Answer 1

Let the number of shirts bought be x and the number of pant bought be y.

x + y = 15 --- (1)
x - y = 7 --- (2)

From (2), we have:

y = x - 7 --- (3)

Substituiting (3) into (1), we will get:

x + x - 7 = 15
2x = 15 + 7
2x = 22
x = 22 / 2
x = 11

Substituting x = 11 into (3), we will get:

y = 11 - 7
y = 4

Thus, x = 11 and y = 4.
Hence, 11 shirts and 4 pants were bought.
