Well, if every box is a unit, it would be 6 units in length.
C because I just did that
Add both the equations together to eliminate x
x+5y=8
-x+2y=-1
7y=7
y=1
Now fill in y into the original equation
x+5(1)=8
x+5=8
x=3
Now you can check by filling x and y into the second equation.
-(3)+2(1)=-1
-3+2=-1
-1=-1
So your answer will be (3, 1)
