35
12 + 25y = 795
12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y= 555
y=15
Substitute y= 15 into
x=y + 20
x= 15 + 20
x= 35
T-shirt = 35
Sweatshirt = 15
They brought 35 t shirts
Answer:
2x+2y=310
x-y=55
multiply seond equation by 2 and adding to first equation
2x-2y=110
add
2x-2y=110
2x+2y=310 +
4x+0y=420
4x=420
divide 4
x=105
sub
x-y=55
105-y=55
minuse 105
-y=-50
mult -1
y=50
the numbers are 105 and 50
