Зу - 2x = -2<br> у+ 2x = 8
Andrew [12]

Answer:

(3.25, 1.5)

Step-by-step explanation:

<em><u>First, turn the 2nd equation into y=mx+b form:</u></em>

у+ 2x = 8

<u>  -2x     -2x</u>

y  =  -2x + 8

<u><em>Next Substitute:</em></u>

З(-2x+8) - 2x = -2

-6x + 24 - 2x = -2

-8x + 24 = -2

<u><em>Then simplify:</em></u>

-8x + 24 = -2

<u>      -24     -24</u>

-8x       = -26

x = 3.25

<em><u>Lastly, substitute x into any one of the original equations:</u></em>

y + 2 (3.25) =8

y + 6.5 = 8

<u>   - 6.5   - 6.5</u>

y  =  1.5
