Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)
Y = 4x

Answer:
1560.38
Step-by-step explanation:
As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.
1560 - 100 = 1460
Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.
Total Cost = 1460 * (1.06875)
Total Cost = 1560.38
Edit
You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.
If the TV cost is 1200 you may not get the rebate.
