### 6.1 multi step w-dist. property 1

1. 1. Lesson 6.1 , For use with pages 293-297 Simplify the expression by combining like terms. 1. 7 x + 9 – 3 x + 2 <ul><li>8 y + 3 x + 5 y – ( – 7 x ) </li></ul>
2. 2. Lesson 6.1 , For use with pages 293-297 Simplify the expression by combining like terms. 1. 7 x + 9 – 3 x + 2 <ul><li>8 y + 3 x + 5 y – ( – 7 x ) </li></ul>ANSWER 4 x + 11 ANSWER 10 x + 13 y
3. 3. Solve Multi-Step Equations Students will solve multi-step equations using different transformations.
4. 4. <ul><li>So far we have solved one-step and two-step equations. </li></ul><ul><li>In this section we will be solving </li></ul><ul><li>MULTI-step equations. </li></ul>
