Answer:

(2,-7)

Explanation:

Solve for x.

Plug in the value for y into the equation.

y=-5x+3

8x+2y=2

8x + 2(-5x+3)=2

8x-10x+6=2

-6 -6

---------------------

8x-10x = 2-6

8x-10x = -4

-2x = -4

÷ -2 ÷ -2

-------------------

x = 2

Solve for y.

Plug in the value for x into the equation.

8x+2y=2

8(2) + 2y=2

16 + 2y = 2

- 16 - 16

----------------------

2y = 2 - 16

2y = -14

÷ 2 ÷2

----------------

y = -7

Solve.

Determine if x and y values work.

8(2)+2(-7)=2

16-14=2

2=2

x and y values work so the answer is: (2,-7)
