Answer:


(-1,-3)

Explanation:


x+6y=-19

Subtract 6y from both sides


x=-19-6y

-----------------------------------------


3x-7y=18

Divide everything by 3


x -(7)/(3)y =6


x=6+(7)/(3)y

Substitute the x value to the other equation


6+(7)/(3)y+6y=-19

Subtract both sides by 6


(7)/(3)y+6y=-25


6(7)/(3)y=-25


(25)/(3)y=-25


y=-3


x+6(-3)=-19


x+-18=-19


x=-1
