What you’ll learn
Given an equation of the form px = q or x / p = q with p nonzero and a unique nonnegative rational solution, solve for x using an inverse operation and verify the result by substitution.
Key idea
Divide both sides by the same nonzero number.
Worked example
Solve for x and verify by substitution.
7x = 56
x = 56 / 7
x = 8
