Example 1 Solving Two-Step Equations SOLUTION a. 12x2x + 5 = Write original equation. 112x2x + – = 15 – Subtract 1 from each side. (Subtraction property of equality) 2x2x4 = Simplify. 2 2x2x = 2 4 Divide each side by 2. (Division property of equality) x2 = Simplify. Solve the equation. Check your solution. a. 512x2x=+ b. 1143x3x= –
