My dad enjoyed jogging at night. He would have his little MP3 player with him listening to either R&B, jazz, or news while he did
this nighly ritual. In a hypothetical situation, Dad had exactly 14 hours and 5 minutes of audio content on his device.
The linear equation 6x+4y+125=845 can help determine how many jazz songs, x, and how many R&B songs, y, Dad on his MP3 player.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this many-words story they invite you to put x = y in their equation
6x + 4y + 125 = 845.
As soon as you do it, you will get
6x + 4x + 125 = 845.
And they want you solve it for x.
It is easy. Simplify the last equation:
10x + 125 = 845 ---> 10x = 845 - 125 ---> 10x = 720 ---> x =  = 72.
Answer. There are 72 the jazz songs and 72 R&B songs in the MP3 player.
The rest of the information in the input is excessive and serves for the only purpose to distract your attention.
Solved.
They only want to test if you are able to separate the significant information from the "noise" in the text.
