Question 16251
First you have to distribute any minus or pluses you have.  You can re-write the equation as 5-y+6-y-5+y=0.  Then you should combine like terms on the left and right.  5+6-5=6 and -y-y+y=-y.  After you've combined like terms you now have 6-y=0.  Subtract a 6 from both sides to get -y=-6, then multiply both sides by -1 to make y positive.  (-1)(-y)=(-1)(-6)  =>  y=6
