Answer:

[tex]\displaystyle [-2, 7][/tex]

Step-by-step explanation:

{4x + 2y = 6

{−2x + 2y = 18

½[4x + 2y = 6]

{2x + y = 3 >> New Equation

{−2x + 2y = 18

__________

[tex]\displaystyle \frac{3y}{3} = \frac{21}{3}[/tex]

[tex]\displaystyle 7 = y[/tex][Plug this back into both equations above to get the x-coordinate of −2]; [tex]\displaystyle -2 = x[/tex]

I am joyous to assist you anytime.
