Answer:
(4, 5)
Explanation:
The system of equation is
x - y = -1
x + y = 9
To solve the system using elimination, we need to add both equations so
x - y = -1
x + y = 9
2x + 0 = 8
Now, we can solve the equation
2x = 8
2x/2 = 8/2
x = 4
Finally, replacing x = 4 on the second equation and solve for y
x + y = 9
4 + y = 9
4 + y - 4 = 9 - 4
y = 5
Therefore, the solution to the system of equation is
x = 4 and y = 5 or the point (4, 5)
