(x+5)/(1-x)<= (3-x)/(x+3)

\frac{x + 5}{1 - x} \leq \frac{3 - x}{x + 3}

- 3 < x \leq - 1 or x > 1

Solution steps

\frac{x + 5}{1 - x} \leq \frac{3 - x}{x + 3}

Rewrite in standard form

\frac{12 x + 12}{( - x + 1 ) ( x + 3 )} \leq 0

Factor

\frac{12 x + 12}{( - x + 1 ) ( x + 3 )} : \frac{12 ( x + 1 )}{( - x + 1 ) ( x + 3 )}

\frac{12 ( x + 1 )}{( - x + 1 ) ( x + 3 )} \leq 0

Divide both sides by

12

\frac{\frac{12 ( x + 1 )}{( - x + 1 ) ( x + 3 )}}{12} \leq \frac{0}{12}

Simplify

\frac{x + 1}{( - x + 1 ) ( x + 3 )} \leq 0

Identify the intervals

- 3 < x \leq - 1 or x > 1
