1. Stating the problem: Solve the equation $\frac{c + 20}{2} = 14$ for $c$. 2. Formula and rules: To solve for $c$, multiply both sides of the equation by 2 to eliminate the denominator. 3. Multiply both sides by 2: $$\cancel{2} \times \frac{c + 20}{\cancel{2}} = 14 \times 2$$ which simplifies to $$c + 20 = 28$$ 4. Subtract 20 from both sides to isolate $c$: $$c + 20 - 20 = 28 - 20$$ which simplifies to $$c = 8$$ 5. Final answer: $c = 8$
