Any rational root of f(x) is a factor of 9 divided by a factor of 12.
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
multipl 10×2=20 y ese es el resultado entendes ?
The simple rules in adding equation is

- then get one variable on one side of the equation
- then solve the rest
