Answer :

Multiply each side of the given equation by 60 to get rid of all the fractions.

You'll wind up with an equation to which the only possible solution is y=0 .

The question is kind of lame, but that's what we have to put up with
while we're taking math.
[tex]y-\frac{y}{2}+\frac{y}{3}-\frac{y}{4}=\frac{y}{5}|\cdot60\\ 60y-30y+20y-15y=12y\\ 23y=0\\ y=0 [/tex]
