Solving Two-Step Equations
- JoAnn Ghianni
The algorithm for solving two-step equations may also be used to solve two-step inequalities.
2x + 8 = 28 (co-efficient) (variable) (constant) 2x+8=28 Step 1 - Add the opposite of the constant to both sides of the equation. 2x + 8 = 28 +(-8) +(-8) 2x = 20 Step 2 - Divide both sides of the equation by the co-efficient. 2x = 20 2 2 x = 10 Your solution!
