Question

Part A

Answer 1

Part A: The algebraic equation for the situation is 2x - 3 = 5

Part B:  Bob has 4 brand new music CD's

Step-by-step explanation:

Translate the situation into an algebraic equation:

• Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
• Find the value of x (the number of brand new CD's Bob has)

Part A:

∵ Bob has x brand new CD's

∵ Ann has 5 brand new music CD’s, which is 3 less than twice

  the amount that Bob has

- That means multiply x by 2 and then subtract 3 from the product

  and equate the answer by 5

∵ Twice x 2x

∵ 3 less than twice x = 2x - 3

∴ 2x - 3 = 5

The algebraic equation for the situation is 2x - 3 = 5

Part B:

Let us solve the equation to find the value of x

∵ 2x - 3 = 5

- Add 3 to both sides

∴ 2x = 8

- Divide both sides by 2

∴ x = 4

Bob has 4 brand new music CD's
