Question

$\frac{x^2-9}{5} =8$

Answer 1

Hey mate,

Just cross multiply and you will get,

x^2 = 49

so x = 7 as 7^2 = 49

Hope this helps you out!

Answer 2

$\frac{x^2-9}{5} =8$
$= > > {x}^{2} - 9 = 8 \times 5 \\ = > {x}^{2} - 9 = 40 \\ = > {x}^{2} = 49 \\ = > x = \sqrt{49} \\ = > x = 7$
x=7
Here is your answer!
