If we add the two equations we get:
-x - 6y + x - 2y = 10 + (-2)
-8y = 8, therefor y = -1

If y = -1:
-x - 6(-1) = 10
-x + 6 = 10
-x = 4
x = -4

Therefor the solution would be (-4, -1)

Ivan has 4 hours of Music on his MP3 player Jazz makes up 1/6 of the total time how many hours of jazz are on Ivan's MP3 player

Crank

So theres 4 hours and 60min equals 1 hour, so multiply 4 by 60 to get 240, so theres 240 minutes of time on the mp3. So 1/6 of that total time (240min) was on jazz, so what you do is divide 240 by 6 to get 40, so every 1/6 is 40min. So you could say he spend 40min listening to jazz, or you could say he spent 2/3 of an hour listening to jazz
