The correct option is A) $x=\frac{y+9+7z}{7}$

Step-by-step explanation:

Consider the provided equation.

y=7x-7z-9

We need to solve the provided equation for x.

Add 9 both side.

y+9=7x-7z

Now add 7z to both side.

y+9+7z=7x-7z+7z

y+9+7z=7x

Divide both sides by 7.

$\frac{7x}{7}=\frac{y+9+7z}{7}$

$x=\frac{y+9+7z}{7}$

Hence, the correct option is A) $x=\frac{y+9+7z}{7}$
