6x+8-4=3x
6x-3x=4-8
3x=-4
x=-4/3
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

The graph starts at $250, as that is the amount invested, and increases exponentially from that point.
Answer:
327.6 €
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
