Best Answer

You have :

--------------

( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 )

Multiply both sides by ( x ) ( x - 12 ) and get :

( x + 1 ) ( x - 12 ) = ( -7 ) ( x )

x^2 - 12x + x - 12 = -7x

x^2 - 4x - 12 = 0

Factor the above :

( x - 6 ) ( x + 2 ) = 0

There are two roots :

x = 6 <------------------

x = -2 <---------------
