Step-by-step explanation:
Because since 17 can only be multiplied by it's self and one that's what the box is showing
So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
