The questioner wants us to list all possible roots by applying the Rational Roots theorem
factors of constant term (-20) = +/- 1, +/-2, +/-5, +/-10, +/-20 WE call these factors p.
factors of leading coefficient (2) = +/- 1, +/-2 (call these q)
then possible roots are p/q = +/-1/1, +/- 1/2 , +/- 5/1 , +/- 5/2 and so on.
Answer:
adding both equations
4x+9y=5
-4x+7y=11
+ + =+
________
0 +16y=16
y=1
putting the value of y in first eqn
4x+9×1=5
4x=5-9
4x=-4
x=-1
so the x is -1 and y is 1
4 to the right and 3 left
