Explain how you worked the problem to find x! 1/x +1/(x+4) =1/5
Answers: 1
(by taking the common factor for the two elements of the equation![\frac{1]{x} *\frac{x+4}{x+4} +\frac{1}{x+4}*\frac{x}{x}=\frac{x+4}{x*(x+4)}+\frac{x}{x*(x+4)}](/tpl/images/0146/0272/c4e39.png)
now we can add both of the equation as the denominators have the same value.
by multiplying both sides by 
by subtracting both sides by (10x+20)
(by using the quadratic formula)
and
