Answer:

$\frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}$

Step-by-step explanation:

$\frac{2x}{4x^2-9} + \frac{3}{2x^2+x-3}$ can be simplified to:
$\frac{2x}{(2x-3)(2x+3)}+\frac{3}{(2x+3)(x-1)}$

Make them have common denominators so:
$\frac{(2x)(x-1) +3(2x-3)}{(2x-3)(2x+3)(x-1)}$

Simplify:
$\frac{2x^2-2x+6x-9}{(2x-3)(2x+3)(x-1)} = \frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}$

I don't think you can simplify that fraction further so that's the answer.

$2x + 9 = 5x$

$5x = 2x + 9$

Subtract sides 2x

$- 2x + 5x = - 2x + 2x + 9$

$3x = 9$

Divide sides by 3

$\frac{3x}{3} = \frac{9}{3} \\$

$x = 3$

CHECK :

$2x + 9 = 5x$

$2(3) + 9 = 5(3)$

$6 + 9 = 15$

$15 = 15$

So the value is correct.
