Last time we solved One-Step and Two-Step Equations.
What do you think a
Multi-Step Equation is?
LET’S SOLVE A MULTI-STEP EQUATION!

1. 18x -4 = 3x + 1
2. 20x + 3 = -10x + 9
3. -2n -5n -6 = 2n – 3n
4. 1 + 5a = 9 + a +2 + 2

YOU TRY IT!
1. 2x + 12 + x = 3(2x – 4)
2. 4(7 + m) = 13 + m
3. -8(5 – 3n) = 40 + 8n 4. 3(4x + 4) – 7x = -23 -2x
