We have 3x+9y=36, or equivalently 12x+36y=144. We also have 12x+4y=18, so subtracting these we have 32y=126 or y=63/16. Substituting this into our original equation leaves 3x=36-9*63/16 or x = 12-3*63/16 = 3/16.
So: x=3/16, y=63/16

If you are talking about f(x) then yes it is the same as y
The lines are parallel, but not the same.
it is the same i believe
We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
No, equations with the same slope do not intersect unless they are the same line.
