Grade 8 · Algebra & Patterning
Solving Two-Step Equations
Two-step equations require students to plan a sequence of inverse operations rather than act on impulse. 3x + 7 = 22 asks: what was done to x, and in what order? Undo in reverse. Equations with variables on both sides introduce a new move — collecting like terms — and deepen algebraic reasoning.
