4x- 2y = 8<br> 2x + y =2
Juli2301 [7.4K]

Answer:

x = 3/2 , y = -1

Step-by-step explanation:

I'm assuming that you are being asked to solve the system of equations for x and y.

given:

4x- 2y = 8  ---------------(1)

2x + y =2 -----------------(2)

We can solve this by elimination:

multiple (2) by 2, we get:

2(2x + y) =2(2)

4x + 2y = 4 ------------(3)

(1) + (3) , we get:

(4x- 2y) - (4x + 2y) = 8 + 4

8x = 12   (divide both sides by 8)

x = 12/8

x = 3/2   answer, substitute this into (2)  

2(3/2) + y =2

3 + y = 2  (subtract 3 from both sides)

y = 2 - 3

y = -1  answer
