Answer 2

Answer:

$x = \frac{25}{7}$

Step-by-step explanation:

$Given \: simple \: equation:\\7x-9=16$

Add both sides by 9, we get

$\implies 7x-9+9 = 16+9$

$\implies 7x = 25$

Divide both sides by 7 , we get

$\implies \frac{7x}{7}=\frac{25}{7}$

$\implies x = \frac{25}{7}$

Therefore,

$x = \frac{25}{7}$
