[tex]8x - 9 = 8[/tex]
+9 +9 (add 9 in both sides)
[tex]8x = 17[/tex]
÷8 ÷8 (divide 8 in both sides)
[tex]x = \frac{17}{8} [/tex]
Here you go
If you don't know how I've done you need to use their inverse operations.

To solve this, first add 9 on both sides.

8x-9+9=8+9

8x=17

Then divide both sides by 8 to find the value of x.

[tex]\frac{8x}{8}[/tex]=[tex]\frac{17}{8}[/tex]

x=[tex]\frac{17}{8}[/tex]

The final answer is x=[tex]\frac{17}{8}[/tex] or 2.125.
