Question

solve it ......please​

Answer 1

Answer:

25/7

Step-by-step explanation:

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

i.e.

$\frac{(x+3)(x-3)}{x+3} = \frac{4}{7}$

Cancelling (x+3) from numerator and denominator gives,

x - 3 = 4/7

i.e. 7x - 21 = 4

i.e. 7x = 25

i.e. x = 25/7

Answer 2

Step-by-step explanation:

x^2-3^2/x+3=4/7

(x+3)(x-3)/x+3)=4/7

cancel x+3 we get

x-3=4/7

cross multiply we get

7x-21=4

7x=25

x=25/7.
