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. Based on this situation, how many R&B songs and jazz songs combined were on my dad's device if the number of songs for each genre was the same? \n" ); document.write( "
