(-10/11,36/11)

Explanation:

Multiply the second equation by 2.

{(5x+2y=2),(6x-2y=-12):}

Add the equations.

11x=-10

color(blue)(x=-10/11

Plug the newfound value for x in to either equation to determine y.

5x+2y=2=>5(color(blue)(-10/11))+2y=2

-50/11+2y=22/11

2y=72/11

color(green)(y=36/11

Write the answers in an ordered pair: (-10/11,36/11)
