Let f%28x%29=+%28x%2B1%29%2F%28x-5%29
f%280%29=%280%2B1%29%2F%280-5%29
f%280%29=1%2F-5
highlight%28f%280%29=-1%2F5%29


f%2835%29=%2835%2B1%29%2F%2835-5%29
f%2835%29=36%2F30
f%2835%29=cross%2836%296%2Fcross%2830%295
highlight%28f%2835%29=6%2F5%29

if f%28x%29=7, what is x
7=+%28x%2B1%29%2F%28x-5%29 ...solve for x
7%28x-5%29=+%28x%2B1%29+
7x-35=+x%2B1+
7x-x=+35%2B1+
6x=+36+
x=+36%2F6+
highlight%28x=+6%29+
