Answer:
The solution is (7, 6)
Step-by-step explanation:
You can find the solution of the system by multiplying the first equation by -3 and then adding together to get x to cancel.
-6x - 3y = -60
6x - 5y = 12
-----------------
-8y = -48
y = 6
Now that we have the y value, we can put it into either equation to find the x value.
2x + y = 20
2x + 6 = 20
2x = 14
x = 7
Therefore the point is (7, 6)
