Question

Arrange the equations in the correct sequence to find the inverse of fx=y=x-4/33-x

Answer 1

F ( x) = y = ( x - 4 ) / ( 33 - x )
( 33 - x ) * y = x - 4
33 y - x y = x - 4
- x y - x = - 33 y - 4   / * ( - 1 )
( we shall multiply both sides of an equation by - 1 ) 
x y + x = 33 y + 4
x ( y + 1 ) = 33 y + 4
x = ( 33 y + 4 ) / ( y + 1 )
Answer:
The inverse function is:
$y = \frac{33x+4}{x+1}$
