Answer:
(x = -6), (y = -6)
(-6,-6)
Step-by-step explanation:
X=-6
3x - 2y = -6
3(-6) - 2y = -6
-18 - 2y = -6
What you do to one side, you do to the other. And when you take it over to the other side, you'll have to turn -18 into a positive 18.
-2y = 18 - 6
-2y = 12
Divide both sides by -2
y = -6

22% = 22/100
22/100 * 14.50 = 3.19 (this is the amount discounted off original price)
14.50 - 3.19 = $11.31
