Answer:

Step-by-step explanation:

3/2x-1+4/2x+1

=3/2x+4/2x

=3+4/2x

=7/2x

Lhs =Rhs

Hence proved.

Answer 2

Answer:

x=7/2

Step-by-step explanation:

⇒3/(2x-1)+4/(2x+1)=7/2x

⇒{4(2x-1)+3(2x+1)}/4x^2-1=7/2x

⇒8x-4+6x+3/4x^2-1=7/2x

⇒14x-1/14x^2-1=7/2x

⇒2x(14x-1)=7(4x^2-1)

⇒28x^2-2x=28x^2-7

⇒-2x=-7                                       (∴28x^2 in LHS and RHS are cancel)

⇒x=7/2                                         (∴Minuses in LHS and RHS are cancel)
