p(x+q)=qx-r

Solution for p(x+q)=qx-r equation:

Simplifying
p(x + q) = qx + -1r

Reorder the terms:
p(q + x) = qx + -1r
(q * p + x * p) = qx + -1r
(pq + px) = qx + -1r

Solving
pq + px = qx + -1r

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Reorder the terms:
pq + px + -1qx + r = qx + -1qx + -1r + r

Combine like terms: qx + -1qx = 0
pq + px + -1qx + r = 0 + -1r + r
pq + px + -1qx + r = -1r + r

Combine like terms: -1r + r = 0
pq + px + -1qx + r = 0
