Solving Two-Step Equations

Two-step equations have the form ax + b = c. You need two operations to solve them.

The Order Matters

Use reverse order of operations:

  1. First: Undo addition or subtraction
  2. Then: Undo multiplication or division

Example: Solve 3x + 5 = 20

Step 1: Subtract 5 from both sides โ†’ 3x = 15

Step 2: Divide both sides by 3 โ†’ x = 5

Check Your Work

Always verify by substituting back: 3(5) + 5 = 15 + 5 = 20 โœ“
