Question

How do you solve this? 2x/3 - 9 = 0

Answer 1

`x=27/2`

Explanation:

`"isolate "(2x)/3" by adding 9 to both sides"`

`(2x)/3cancel(-9)cancel(+9)=0+9`

`rArr(2x)/3=9`

`"multiply both sides by 3"`

`cancel(3)^1xx(2x)/cancel(3)^1=3xx9`

`rArr2x=27`

`"divide both sides by 2"`

`(cancel(2) x)/cancel(2)=27/2`

`rArrx=27/2" is the solution"`

Answer 2

`x=13.5`

Explanation:

`(2x)/3 -9 =0`

Take `9` to other side it will add to zero

`(2x)/3=0+9`

`(2x)/3=9`

Then,

`2x=9*3`

`2x=27`

`x=27/2`

`x=13.5`

Answer 3

`x=13.5`

Explanation:

First of all, you have to eliminate `9`, so you add `9` on both sides. Now the equation is

`(2x)/3=9`

After that, you have to move `3` to the other side so you can solve for `x`, so you multiply by `3` on both sides. The equation becomes

`2x=27`

After that, you divide by `2` on both sides and

`x= 13.5`

To check your answer, replace `13.5` in for `x` in the original equation, which would be

`(2(13.5))/3 - 9 = 0`

Answer 4

`x=27/2 = 13.5`

Explanation:

`(2x)/3-9 = 0`

`(2x)/3= 9`

`2x= 27`

`x= 27/2 = 13.5`
