1. Solve Multi-Step
Equations
Section 3.3
P. 148 -153
Students will solve multi-step equations using
different transformations.

2. • So far we have solved
one-step and two-step equations.
• In this section we will be solving
MULTI-step equations.

3. Steps
• 1) Simplify both sides
( may include the distributive property,
combining like terms,
change subtraction to “add the opposite)
• 2) Addition/Subtraction transformations
• 3) Simplify
• 4) Multiplication/Division transformations
• 5) Simplify

4. Students will solve multi-step equations using
different transformations.
• Solve:
7x + 2(x + 6) = 39

5. Students will solve multi-step equations using
different transformations.
• Solve:
4x - 7(x – 2) = 26

6. Students will solve multi-step equations using
different transformations.
