Given :   (x + 3)/7  -  (2x-5)/3  =  (3x - 5)/5  - 25

To Find :  x  

Verify

Solution:

(x + 3)/7  -  (2x-5)/3  =  (3x - 5)/5  - 25

Multiply both sides by 5 * 7 * 3

=> 15(x + 3)  - 35(2x - 5)  = 21(3x - 5)  - 25*105

=> 15x + 45 - 70x + 175  = 63x - 105  - 25*105

=> -55x  + 220  = 63x - 105*26

=> 118x = 105*26 + 220

=> 118x  = 2950

=> x  = 25

LHS  =

(x + 3)/7  -  (2x-5)/3

= (25 + 3)/7  - ( 50 - 5)/3

= 4  - 15

= - 11

RHS

=  (3x - 5)/5  - 25

= (75 - 5)/5  - 25

= 14 - 25

= - 11

LHS = RHS = - 11
