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]
