So we have the following equation:
[tex] \frac{x}{9}+8=8 [/tex]
In order to start solving this, we need x on one side by itself. So let's subtract 8 from both sides:
[tex] \frac{x}{9}=0 [/tex]
Then, in order to get x, we need to multiply both sides by the number that x is being divided by - in this case, 9. Let's do that:
[tex] 9(\frac{x}{9})=0(9) [/tex]
[tex]x=0[/tex]
So now we know that the value of x is 0.
