Question

plz explain and answer ​

Answer 1

Answer:

$x = \frac{5}{13}$

Step-by-step explanation:

In the very FIRST STEP:-

We have cross mulitplied the denominator as we have learnt in earlier classed to solve fractions.

Nextly,

when we got,

$\frac{15x - 1}{9 {x}^{2} - 1} = \frac{5}{3x}$

we again cross multiplied the 3x to 15x-1 and 9x²-1 to 5.

so,

we got the value as,

-13x= -5

=>

$x = \frac{5}{13}$

and which is the required answer!

Answer 2

Simplify:

Step-by-step explanation:

$\ Given \ value: \\\\\frac{2}{3x-1} +\frac{3}{3x+1}= \frac{5}{3x}\\\\\ Solution:\\\\\frac{2}{3x-1} +\frac{3}{3x+1}= \frac{5}{3x}\\\\\rightarrow \frac{2(3x+1)+3(3x-1)}{(3x-1)(3x+1)}= \frac{5}{3x}\\\\\rightarrow \frac{6x+2+9x-3}{((3x)^2-(1)2)}= \frac{5}{3x}\\\\\rightarrow \frac{15x-1}{(9x^2-1)}= \frac{5}{3x}\\\\\rightarrow \ 3x (15x-1)= 5(9x^2-1)\\\\\rightarrow \ 45x^2-3x= 45x^2-5\\\\\rightarrow \ -3x= -5\\\\\rightarrow \ x= \frac{5}{3}$
