Solve two-step equations and justify each inverse operation.
Solve a two-step equation with a divided variable
Problem
Solve \(x/4~+~3~=~8\).
Big Picture
What this problem is really about
Work backward through the two operations: the addition occurred after x was divided by four, so undo that addition first. With the quotient isolated, multiplication by four reverses the division. Substitution should then reproduce eight and confirm that both inverse steps preserved equality.
