Amanda is shopping for clothing at a store. She can buy 3 shirts for x dollars
apiece and one pair of socks for $7. For
the same amount of money, she can buy
2 shirts for x dollars apiece and a pair of
jeans for $18. Which equation could be
used to find x, the cost of each shirt?

First you need to set up your equation.

If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:

3x+7= 2x+18

You want to find out x in both equations so I’ll help step by step

1. Subtract 2x from both sides

This leaves you with x+7=18

2. Then subtract 7 on both sides

This leaves you with x=11

So x equals 11 for equations.

You can check by plugging in 11 in x. If you get 40 on both sides

CONGRATS!! You did it

I hope this helped. Have a great day!
