Let f(x) = x/(x-6). Find a function y=g(x) so that (f o g)(x)=2x.

earnstyle [38]

Solve as a simultaneous equation maybe?
f(x) + g(x) = 2x or x/(x-6) + y =2x
and then solve so it becomes 2x^2 + 5x =y
then factorise into brackets or use quadratic formula

m_a_m_a [10]

-7.2x + 8.7x = -3.5 - 10

x = -13.5/1.5
x = -9

Write a system of equations and solve

Semenov [28]

$c+b=7$
$5c+45b=195$

$c+b=7$ --> $c=7-b$
$5c+45b=195$

$5(7-b)+45b=195$
$35-5b+45b=195$
$35+40b=195$
$40b=160$
$b=4$

$c+(4)=7$
$c=3$

$cars:3 \\ 
buses:4$

And object is traveling at a steady speed of 8 2/3 mph how long will it take to object to travel 5 1/5 miles

LenaWriter [7]

$\bf \begin{array}{ccll}
miles&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
8\frac{2}{3}&1\\\\
5\frac{1}{5}&h
\end{array}\implies \cfrac{8\frac{2}{3}}{5\frac{1}{5}}=\cfrac{1}{h}\implies \cfrac{\quad \frac{26}{3}\quad }{\frac{26}{5}}=\cfrac{1}{h}\implies \cfrac{26}{3}\cdot \cfrac{5}{26}=\cfrac{1}{h}
\\\\\\
\cfrac{5}{3}=\cfrac{1}{h}\implies 5h=3\implies h=\cfrac{3}{5}$

which is just 36 minutes.
