Accepted Answer

x	$$\frac{x+5}{x-3}$$
-13	$$\frac{-13+5}{-13-3} = \frac{-8}{-16} = \frac{1}{2}$$
-5	$$\frac{-5+5}{-5-3} = \frac{0}{-8} = 0$$
-0.2	$$\frac{-0.2+5}{-0.2-3} = \frac{4.8}{-3.2} = -1.5$$
0	$$\frac{0+5}{0-3} = -\frac{5}{3} = -1\frac{2}{3}$$
1	$$\frac{1+5}{1-3} = \frac{6}{-2} = -3$$
17	$$\frac{17+5}{17-3} = \frac{22}{14} = \frac{11}{7} = 1\frac{4}{7}$$
$$\frac{5}{3}$$	$$\frac{\frac{5}{3}+5}{\frac{5}{3}-3} = \frac{\frac{5+15}{3}}{\frac{5-9}{3}} = \frac{\frac{20}{3}}{\frac{-4}{3}} = \frac{20}{-4} = -5$$
7	$$\frac{7+5}{7-3} = \frac{12}{4} = 3$$
