Answer 2

Heya ✌✌
Here is u r Ans ➡➡➡

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

$= \frac{x {}^{2} - 9 }{x {}^{2} + 3 } = \frac{4}{7}$

$= 7(x {}^{2} - 9) = 4(x {}^{2} + 3)$

$= 7x {}^{2} - 63 = 4x {}^{2} + 12$

$= 7x {}^{2} - 4x {}^{2} - 63 = 12$

$= 7 x{}^{2} - 4x {}^{2} = 12 + 63$

$= 3x {}^{2} = 12 + 63$

$= 3x {}^{2} = 75$

$x {}^{2} = 25$


$x = 5 \\ x = - 5$
