Question 4947
multiply the equation by 5 to clear the denominator, your new equation is:
25+w-5w=15
consolidate like terms:
25-4w=15
subtract 25 from both sides:
-4w=-10
divide both sides by -4 and reduce:
{{{w=5/2}}}

verify by plugging it into the original equation:
{{{5+(5/2)/5-(5/2)=15}}}

This is a true statement, so w=5/2
