Question 94229
Subtract: Express your answer in simplist form:
2/5-y/y-2 
:
Assume you mean (a few brackets would take the guesswork out of this):
{{{2/5}}} - {{{y/((y-2))}}}
:
The common denominator would be 5(y-2) so you have:
{{{(2(y-2) - 5y)/(5(y-2))}}} = {{{(2y - 4 - 5y)/(5(y-2))}}} = {{{(-3y - 4 )/(5(y-2))}}}
