Answer 2

Answer:

7/2

Step-by-step explanation:

3/(2x-1)+4/(2x+1)=7/2x

find the lcm of these fractions

simple rule to find lcm of fractions do the cross-multiplication

3(2x+1)+4(2x-1)

--------------------- = 7/2x

(2x) ^2-(1)^2

using identity (a+b)(a-b) =a^2-b^2

6x+3+8x-4

---------------=7/2x

4x^2-1

14x-1. 7

------- = ------

4x^2-1 2x

again cross multiplication

28x^2-2x=28^2-7

-2x=-7

x=7/2
