Help pls :) solve x+4/3 = 3/x-4

Sonja [21]

Answer:

x= 5 or x= -5

Step-by-step explanation:

$\frac{x + 4}{3} = \frac{3}{x - 4}$

Cross multiply:

(x +4)(x -4)= 3(3)

Expand:

$\boxed{a {}^{2} - {b}^{2} = (a + b)(a - b)}$

x² -4²= 9

x² -16= 9

+16 on both sides:

x²= 9 +16

x²= 25

Square root both sides:

$x = ± \sqrt{25}$

x= 5 or x= -5
