Answer:
(3,-1)
Step-by-step explanation:
2x -7y = 13
3x+y = 8
Multiply the second equation by 7
7(3x+y) = 7*8
21x +7y = 56
Add this to the first equation to eliminate y
2x -7y = 13
21x +7y = 56
-----------------------
23x = 69
Divide each side by 23
23x/23 = 69/23
x = 3
3x+y = 8
3(3) +y = 8
9+y = 8
Subtract 9 from each side
9-9 +y =8-9
y = -1
(3,-1)
