    This is how i do these. find a lcm and multiply all your fraction by it inorder to clear the fractions. then you will distribute into the quanities. transpose varibles and constants and divde by the coeficient infront of your variable.

    So after clearing the fractions you end up with 8(y+2)-10(y-1)=15(y-3)

    8y+16-10y+10=15y-45

    divide both sides by 17 you end up with 61/17=y

    Just remember if you do it to a fraction to clear it you must do it to all the remaining quanties in the equation unless they are in perenthises
