  1. Bell Work 9/17/14 Solve the equation.

  2. Yesterday’s Homework • Any questions? • Please pass your homework to the front. • Make sure the correct heading is on your paper. • Is your NAME on your paper? • Make sure the homework is 100% complete. • Incomplete work will NOT be accepted.

  3. Heading 1/7/2020 Solving Multi-Step Equations (multi-step) TSWBAT: solve multi-step equations. Students solve multi-step problems, including word problems, involving linear equations and linear inequalities in one variable and provide justification for each step.

  4. Notes • Steps for Solving Linear Equations • Simplify both sides of the equation. • Distribute and/or combine like terms. 2. Collect the variables to one side of the equation. • Collect to the side with the greater variable. 3. Use inverse operations to isolate the variable. • PEMDAS backwards. • The Golden Rule (of Mathematics) What you do to one side, you must do to the other.

  5. Notes Now you try. Solve the equation. Ex. Ex. Distribute first. Combine the like terms. What operation next? What operation next?

  6. Notes Solve the equation. Ex. Distribute first. Combine the like terms. What operation next? What operation next?

  7. Notes Now you try. Solve the equation. Ex. Distribute first. Combine the like terms. What operation next? What operation next?

  8. Summary To solve a multi-step equation first _________ to get rid of the parenthesis. Next ________ any like terms. You now have a regular two-step equation to solve. Just ____/subtract and then multiply/______ to isolate the ________. distribute combine add divide variable

  9. Ticket Out the Door Complete the Ticket Out the Door without talking!!!!! Talking = time after the bell! Put your NAME on the paper. When finished, turn your paper face DOWN. Solve the equation.
