Answer:-

3x-4 /7 +7/3x-4 =5/2

according to the question....

7+(3x-4)/ 7 ×(3x-4)= 5/2

7+ 3x -4 / 21x- 28= 5/2

3x +7-4 /21x-28=5/2

3x+3 /21x-28=5/2

Here we have to do cross multiplication.

2(3x+3)= 5 ( 21x-28)

6x+6= 105 x-140

6x-105x= -140-6

-99x =-146

x= -146/-99

x=146/99

because both -(minus) are cancelled..

so the value of x=146/99

hope it helps you..
