Question

????? help out ( not good with math )

Answer 1

The answer is x = 3

Explanation:

5x + 9 = 24

5x +9 -9 = 24 - 9

5x = 15

x = 15/5 = 3

Therefore, x = 3

Kelly multiplied 5 to each side when she solved for x, which is incorrect.

Answer 2

Kelly had incorrectly solved for
`x` where she had multiplied by
`5` instead of dividing by
`5` to find for
`x`.

Explanation:

How Kelly should have solved it:

`5x+9 = 24`

`5x + 9-9= 24-9`

`5x=15`

`5x/ 5=15/ 5` (mistake occurred during this step in Kelly's work where she had multiplied by
`5`)

`x=3`

Checking:

To check if
`x=3`, we can use substitution:

`5x+9 = 5(3)+9`

`=15+9`

`=24`

∴ The solution for
`x` is correct.

Hope this helps :)
