Question

$\frac{9x - 7}{3x + 5} = \frac{3x - 4}{x + 6}$
please give me answer who give me answer I will mark him brainlist​

Answer 1

Given:

$\frac{9x-7}{3x+5} =\frac{3x-4}{x+6}$

To Find:

x= ?

Solution:

$\frac{9x-7}{3x+5} =\frac{3x-4}{x+6}$

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

$9x^2-42-7x+54x=9x^2+15x-12x-20$

                -42+47x  = 3x-20

                   47x-3x = 42-20

                        44x = 22

                             x = $\frac{22}{44}$

                             x = $\frac{1}{2}$

i.e.                         x = 0.5
