It can be written as

{2x-(7-5x)}6=7{9x-(3+4x)} (since cross multiplication)

=>(2x-7+5x)6=7(9x-3-4x)

=>(7x-7)6=7(5x-3)

=>42x-42=35x-21

=>42x-35x=42-21
=>7x=21

=>x=3 is your answer


mayonanpatel: We will just do cross multiplication,
6{2x-(7-5x)} = 7{9x-(3+4x)}
6{2x-7+5x} = 7{9x-3-4x}
6{7x-7} = 7{5x-3}
42x-42 = 35x-21
7x = 21
x= 3.

Hi friend...
__________

Here's your answer.....
__________________

2x -(7-5x)/ 9x-(3+4x) = 7/6

or, 2x-7+5x / 9x-3-4x = 7/6

or, 7x-7 / 5x-3 = 7/6

or, 42x-42 = 35x- 21

or, 7x = 21

or, x = 3
