Elaine bought a total of 15 shirts and pants. she bought 7 more shirts than pants. how many of each did she buy?

Step-by-step explanation:

First, set up your equations.

Elaine bought 11 shirts and 7 pants.

We know that she bought 15 shirts, so her shirts + pants is equal to her amount.

s + p = 15

We also know that she bought 7 more shirts than pants, so pants + 7 = shirts.

s = p + 7

Since the second equation already has an isolated variable, let's swap it into the first equation.

(p+7) + p = 15

2p + 7 = 15

2p = 8

p = 4

Since we found shirts, we can now find pants.

s = p + 7

s = (4) + 7

s = 11
