Answer:
The solution to the system would be (3, -1)
Step-by-step explanation:
You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.
-5x + 20y = -35
5x + 9y = 6
-----------------
29y = -29
y = -1
Now that we have the value of y, we can plug it into either equation and find the x value.
x - 4y = 7
x - 4(-1) = 7
x + 4 = 7
x = 3
