- What is, m/n = p-6. Solve for n.
Variable n cannot be equal to 0 as division by zero is not defined. Multiply both sides of the equation by n.
Swap sides so that all variable terms are on the left-hand side.
Combine all terms containing n.
Divide both sides by p-6.
Cancel (p-6) by p-6.
Variable n cannot be equal to 0.
