Multi-Step Equations
📋 What it is
Simplify each side (combine like terms, clear parentheses), then undo step by step.
🗣️ Coach says
Longer equations aren't harder — just more housekeeping. First tidy each side (combine like terms, expand brackets). THEN it becomes a two-step equation you already know. Tidy first, solve second.
🧠 Memory hook
Tidy each side FIRST (combine like terms), THEN peel. Don't solve a messy side.

😲 Whoa!
Engineers solving for an unknown force in a bridge use the exact same "simplify then isolate" routine — just with longer expressions.
✅ Quick check: First move for 2x + 3x − 4 = 11?
Say your answer out loud first — then reveal.
Combine like terms: 2x + 3x = 5x, giving 5x − 4 = 11.
Simplifying each side first turns it into a familiar two-step equation.
🧪 Try it! (2 minutes)
Write 3x + 2x + 1 = 11, combine the x-terms, then solve. Notice how tidying makes it easy.
