Answer:

The correct option is A) [tex]x=\frac{y+9+7z}{7}[/tex]

Step-by-step explanation:

Consider the provided equation.

[tex]y=7x-7z-9[/tex]

We need to solve the provided equation for x.

Add 9 both side.

[tex]y+9=7x-7z[/tex]

Now add 7z to both side.

[tex]y+9+7z=7x-7z+7z[/tex]

[tex]y+9+7z=7x[/tex]

Divide both sides by 7.

[tex]\frac{7x}{7}=\frac{y+9+7z}{7}[/tex]

[tex]x=\frac{y+9+7z}{7}[/tex]

Hence, the correct option is A) [tex]x=\frac{y+9+7z}{7}[/tex]
