Alonzo used a total of 2 and 5/6 gallons of gas while driving his car. each hour he was driving, he used 3/10 gallons of gas. what was the total number of hours he was driving?

That would be 2 5/6  / 3/10

= 17/6 / 3/10

= 17/6 * 10/3

= 85/9

= 9 4/9 hours answer

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
