Answer:
You will need to use simultaneous equations.
Method:
Get both equations to have the same subject, in this case we will multiply the first equation by 4
1) 2x-y = -1
Becomes
1) 8x-4y = -4
Then make both equations equal to 4y.
1) 8x+4= 4y
2) 4y = -5x + 17
Because they both equal 4y, that means they are equal to each other.
8x+4 = -5x+17
Now solve for x.
13x = 13
x = 1
Now that we have x, we can substitute it back into either equation to get y. I will use equation 1 because it is less complex.
2x-y = -1
2(1)-y = -1
y = 3
