There are five unknowns here: p, q, r, x, y
If p, x, q, and y are unknowns, then the equation is not solvable. If p, q, and r are constants, then add the two equations
px+ qy=r
px -qy=r
adding
2px=2r
x= r/p then solve for y, which has to be zero, or q is zero.
As it is, the equation systems cannot be solved.
