Answer:

(3.25, 1.5)

Step-by-step explanation:

First, turn the 2nd equation into y=mx+b form:

у+ 2x = 8

 -2x     -2x

y  =  -2x + 8

Next Substitute:

З(-2x+8) - 2x = -2

-6x + 24 - 2x = -2

-8x + 24 = -2

Then simplify:

-8x + 24 = -2

     -24     -24

-8x       = -26

x = 3.25

Lastly, substitute x into any one of the original equations:

y + 2 (3.25) =8

y + 6.5 = 8

  - 6.5   - 6.5

y  =  1.5

please give me brainliest i worked hard on this :,)

and its 1000% correct, i checked it i promise
