3x - 2y = 5
-2x + 2y = -2
--------------------add
x = 3
3x - 2y = 5
3(3) - 2y = 5
9 - 2y = 5
-2y = 5 - 9
-2y = -4
y = -4/-2
y = 2
solution is (3,2)
ur system of equations is : 3x - 2y = 5 : -2x + 2y = -2
Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong.
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.
45.99 / 3 = 15.33
15.33 x 7 = 107.31
