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
