  • 5-12 Solving Multiplication and Division Equations

    1. 1. 5-12 Solving Multiplication & Dividing Equations Math Notes Algebra and Functions 1.1
    2. 2. Skills Needed...
    3. 3. Skills Needed... Tell what you would do to get the variable alone.
    4. 4. Skills Needed... Tell what you would do to get the variable alone. x ÷ 20
    5. 5. Skills Needed... Tell what you would do to get the variable alone. x ÷ 20 Multiply by 20
    6. 6. Properties of Equality
    7. 7. Properties of Equality You can multiply the same number to both sides of an equation.
    8. 8. Properties of Equality You can multiply the same number to both sides of an equation. You can divide the same number from both sides of an equation.
    9. 9. Example 1 2 x 4= 8
    10. 10. Example 1 2x4 =8
    11. 11. Example 1 2 x 4 ÷ 4 = 8÷ 4
    12. 12. Example 1 2 x 4 ÷ 4 = 8÷ 4 2 = 2
    13. 13. Example 2 30 ÷ 6 = 5
    14. 14. Example 2 30 ÷ 6 =5
    15. 15. Example 2 30 ÷ 6 x 6= 5 x 6
    16. 16. Example 2 30 ÷ 6 x 6= 5 x 6 30 = 30
    17. 17. Example 3 Solve p x 5 = 25
    18. 18. Example 3 Solve p x 5 = 25 STEP ONE: What can you do to get the variable alone?
    19. 19. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone?
    20. 20. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone? STEP TWO: Use the Property of Equality and divide by 5 on both sides.
    21. 21. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone? STEP TWO: Use the Property of Equality and divide by 5 p x 5 ÷ 5 = 25 ÷ 5 on both sides.
    22. 22. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone? STEP TWO: Use the Property of Equality and divide by 5 p x 5 ÷ 5 = 25 ÷ 5 on both sides. STEP THREE: x 5 ÷ 5 cancel out. What is 25 ÷ 5?
    23. 23. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone? STEP TWO: Use the Property of Equality and divide by 5 p x 5 ÷ 5 = 25 ÷ 5 on both sides. STEP THREE: x 5 ÷ 5 cancel out. What is 25 ÷ 5?
    24. 24. Example 3 Solve p x 5 = 25 STEP ONE: What can you do Divide by 5 to get the variable alone? STEP TWO: Use the Property of Equality and divide by 5 p x 5 ÷ 5 = 25 ÷ 5 on both sides. STEP THREE: x 5 ÷ 5 cancel out. p = 5 What is 25 ÷ 5?
    25. 25. Example 4 Solve n ÷ 4 = 7
    26. 26. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do to get the variable alone?
    27. 27. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone?
    28. 28. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone? STEP TWO: Use the Property of Equality and multiply by 4 on both sides.
    29. 29. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone? STEP TWO: Use the Property of Equality and multiply by 4 on both sides. n÷4x4=7x4
    30. 30. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone? STEP TWO: Use the Property of Equality and multiply by 4 on both sides. n÷4x4=7x4 STEP THREE: ÷ 4 x 4 cancel out. What is 7 x 4?
    31. 31. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone? STEP TWO: Use the Property of Equality and multiply by 4 on both sides. n÷4x4=7x4 STEP THREE: ÷ 4 x 4 cancel out. What is 7 x 4?
    32. 32. Example 4 Solve n ÷ 4 = 7 STEP ONE: What can you do Multiply by 4 to get the variable alone? STEP TWO: Use the Property of Equality and multiply by 4 on both sides. n÷4x4=7x4 STEP THREE: ÷ 4 x 4 cancel out. n = 28 What is 7 x 4?
