  1. Do Now 1/25/10 • Take out HW from Friday. • Text page 245, #16-34 evens, #37 • Copy HW in your planner. • Text page 249, #12-32 evens • In your notebook, answer the following question. Draw a picture of what an equation looks like to you. Then give an example of a multiplication and division equation.

  3. Remember this??? EQUATION – mathematical sentence formed by placing an “=“ between two expressions 22 = 14 + z y– 8 = 12 5 ÷ x = 30 11a = 121

  4. Equation Remember this??? x + 7 = 10 Left side Right side ‘x’ has to be 3 in order to make the equation balanced. Like a scale, the left side and right side must be the same in order to be balanced!

  5. Equation 4 7 x = 10 Right side Left side Like a scale, the left side and right side must be the same in order to be balanced!

  6. Objective • SWBAT use multiplicative inverses to solve equations.

  7. Section 5.6, “Using Multiplicative Inverses to Solve Equations” MULTIPLICATIVE INVERSE = RECIPROCAL

  8. MULTIPLICATIVE INVERSE– the product of a number and its multiplicative inverse is 1.

  9. Solve for x. Multiply each side of the equation by the MULTIPLICATIVE INVERSE of 4/7 Multiply -3 Divide (cancel) common factors 1

  10. Try It Out!!Solve

  11. Solving Multi-Step Equations Remember this??? How can you get the “unknown” by itself?

  12. Solve for x. Subtract 4/5 from each side. Write fractions using LCD Multiply each side of the equation by the MULTIPLICATIVE INVERSE of -7/15 -1 Multiply Divide (cancel) common factors 1

  13. Try It Out!!Solve
