I spent $40.00 on a sweater and a shirt. The sweater cost $12.00 more than the shirt. How do I figure this out. I thought the answer was $28.00 but that is not right

Ms. Sue,
40  12 = 28
28/2 = $14 cost of shirt
14 + 12 = $26 cost of sweater

Jen,
x + y = 40
x = y + 12
Use substitution to plug the second equation into the first.
y + y + 12 = 40
2y + 12 = 40
2y = 28
y= 14
Plug y = 14 back into either top equation, x = 26

mimi,
two eqtns....X+12=Y;AND X+Y=40......fromX+12=y thenX+X+12=40;2X+12=40 THEREFORE X=14....IF X=14 AND X+Y=40,THEN Y=26ANS...26DOLLARS FOR SWEATER.
