  1. Bell Work 9/8/14 Evaluate the expression.

  2. Next Chapter Chapter 2 Equations

  3. Heading 1/2/2020 Solving One-Step Equations (add + subtract) TSWBAT: solve one-step equations using addition and subtraction. 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 • Linear Equations • the exponent of the variable(s) is one. • variable is not in the denominator, inside a square root symbol, or inside an absolute value symbol. Linear Equation Not a Linear Equation

  5. Notes • Solving Equations • Goal: to get the variable by itself on one side of the equation. This is known as isolating the variable. • This is also called solving (to solve) an equation. • When we solve an equation, we find the value that makes the equation TRUE, called the solution.

  6. 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.

  7. Notes • Inverse Operations = Inverse means opposite The inverse of … • addition is subtraction. • subtraction is addition. • multiplication is division. • division is multiplication.

  8. Notes Solve the equation. Ex. Ex. Ex. What is the inverse? What is the inverse? Check your answer! Check your answer! Now you try. Ex. Ex. Ex.

  9. Notes Solve the equation. Ex. Ex. Ex. What is the inverse? What is the inverse? Check your answer! Check your answer! Now you try. Ex. Ex. Ex.

  10. Notes Solve the equation. Ex. Ex. Ex. What is the inverse? What is the inverse? Check your answer! Check your answer! Now you try. Ex. Ex. Ex.

  11. Summary Write a summary about today’s lesson. To solve equations involving addition or ___________ just do the inverse operation. If the problem has addition, do ___________, if the problem has subtraction, do ________. If you ever have a double negative do leave, _______, change. subtraction subtraction addition change

  12. 9/8 Ticket Out the Door Complete the Ticket Out the Door without talking!!!!! Put your NAME & class hour on the index card. When finished, turn your index card face DOWN. Solve the equation.

  13. Today’s Homework Rules for Homework • Pencil ONLY. • Must show all of your work. • NO WORK = NO CREDIT • Must attempt EVERY problem. • Always check your answers.
