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 <---------------

What is the answer to this problem If 1 plus 5 equals 12 and 2 plus 10 equals 24 and 3 plus 15 equals 36 then 5 plus 25 equals what?
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
