How to solve px = q using an equation

x = (r - q) / p.

Step-by-step explanation:

Subtract q from both sides if positive or add q to both sides if negative. This gives you px + q - q = r - q, which simplifies to px = r - q.

Divide by p on both sides. This gives you px / p = (r - q) / p, which simplifies to x = (r - q) / p.
