Step-by-step explanation:
You have two equations and two "unknowns" x and y.
This is an easy one. Add the two equations together, which will eliminate the y terms so you can solve for x:
2x+2y = -2
3x-2y = 12
---------------
5x = 10, so x = 2.
Now plug the 2 back into one of the equations and solve it for y.
2(2)+2y = -2
4+2y = -2
2y = -6
y = -3
Let s equal the cost per shirt.
First, we are going to multiply the cost of one shirt to the sale of 25%
0.25s
Second, we are going to multiply by 3 since you are buying 3 shirts.
* 3
Put together.
0.25s * 3
Best of Luck!
