X is t shirt is $8

Y is sweatshirt $11

2x+2y=38

3x+1y=35

We will be using the elimination process so you want even them out same value

2x+2y=38

-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)

-4x=-32

Divide both -4

X=8 So 8 dollars a t-shirt so now will fill x with 8

2(8)+2y=38

16+2y=38

-16

2y=22

Divid by 2

Y = 11 so a sweatshirt is 11 dollars

You can check by fill each by the variable
