Question

Abhi has 8cDs, which is 2 less than twice the number of cDs mithali has. find the number of cDs mithali has​

Answer 1

Answer:

5

Step-by-step explanation:

Let the number of CDs of Mithali be x

We know that,

2x-2= Number of CDs Abhi has

2x-2=8

2x=8+2

2x=10

×=10÷2

x=5

Hence, the number of CDs Mithali has is 5

Answer 2

Step-by-step explanation:

Let the number of DVDs = x

Let the number of CDs = 2x - 3

 

The total of the number of items is 27.

 

x + (2x - 3) = 27

 

 

Solve for x.

 

3x - 3 = 27

3x = 30

  x = 10

 

Plug in this value of x into the number of CDs variable and you will have your solution.
