Answer:

(0,3)

Explanation:

we have

7x-2y=-6 ----> equation A

8x+y=3 ----> equation B

Multiply the equation B by 2 both sides

2(8x+y)=2*3

16x+2y=6 ------> equation C

Adds equation A and equation C

$7x-2y=-6\\16x+2y=6\\--------\\7x+16x=-6+6\\23x=0\\x=0$

Find the value of y

7(0)-2y=-6

-2y=-6

y=3

the solution is the point
