Question:

____________

9x-7÷3x+5=3x-4÷x+6 find x

Answer:

__________

9x - 7 = 3x - 4

3x + 5 x + 6

=> ( 9x - 7 )( x + 6 ) = ( 3x - 4 )( 3x + 5 )

=> 9x( x + 6 ) -7( x + 6 ) = 3x( 3x + 5 ) -4( 3x + 5 )

=> 9x^2 + 54x - 7x - 42 = 9x^2 + 15x - 12x - 20

=> 9x^2 + 47x - 42 = 9x^2 + 3x - 20

=> 9x^2 - 9x^2 + 47x - 3x = - 20 + 42

=> 44x = 22

=> x = 22/44

=> x = 1/2
