Solution for P(r+s)=q equation:


Simplifying
P(r + s) = q
(r * P + s * P) = q
(rP + sP) = q

Solving
rP + sP = q

Solving for variable 'r'.

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

Add '-1sP' to each side of the equation.
rP + sP + -1sP = q + -1sP

Combine like terms: sP + -1sP = 0
rP + 0 = q + -1sP
rP = q + -1sP

Divide each side by 'P'.
r = qP-1 + -1s

Simplifying
r = qP-1 + -1s
