Answer:
The solution set would be (-5, 7)
Explanation:
To find the solution to the system. simply add them together. This will cause y to cancel and allow you to solve for x.
-x + 5y = 30
10x - 5y = -75
--------------------
9x = -45
x = -5
Now we can place that value into either equation and solve for y.
-x + 5y = 30
-(-5) + 5y = 30
5 + 5y = 30
5y = 35
y = 7
