Arely has 4 fewer than twice as many music files as Valerie. They have a combined number of 86 music files. Which is the number

tankabanditka [31]

Answer:

56 music files

Step-by-step explanation:

From the above question:

Let the number of music files

Arely has = x

Valerie has = y

Arely has 4 fewer than twice as many music files as Valerie.

x = 2y - 4

They have a combined number of 86 music files.

x + y = 86

We substitute 2y - 4 for x in the above equation

2y - 4 + y = 86

3y - 4 = 86

3y = 86 + 4

3y = 90

Divide both sides by 3

3y/3 = 90/3

y = 30

Hence, Valerie has 30 music files.

The number of music files that Arely has is calculated as:

x = 2y - 4

x = 2(30) - 4

x = 60 - 4

x = 56

Arely has 56 music files
