Answer:

-5x+y=35x-2y=2

Rewrite it, {-5x+y=2, 3x-2y=2}

Multiply both sides of the first equation by 2, {-10x+2y=4, 3x-2y=2}

Eliminate a variable, -7x=6

Divide both sides by -7, x=-6/7

Substitute the value of x, 3(-6/7)-2y=2

Possible solution, y=-16/7

Now to check the solution, (x, y)=(-6/7, -16/7)

Simplify, -5(-6/7)-16/7=3(-6/7)-2(-16/7)=2

The ordered pair, 2=2=2

Answer, (x,y)=(-6/7,-16/7)
