Question

What is the answer for this thing below? and how you've done it.

`8x - 9 = 8`

Answer 1

`8x - 9 = 8`
+9 +9 (add 9 in both sides)

`8x = 17`
÷8 ÷8 (divide 8 in both sides)

`x = (17)/(8)`
Here you go
If you don't know how I've done you need to use their inverse operations.

Answer 2

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.

`(8x)/(8)`=
`(17)/(8)`

x=
`(17)/(8)`

The final answer is x=
`(17)/(8)` or 2.125.
