Question

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

Answer 1

Answer:

The answer is x = 3

Step-by-step 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

Answer:

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

Step-by-step explanation:

How Kelly should have solved it:

$5x+9 = 24$

$5x + 9-9= 24-9$

$5x=15$

$5x\div 5=15\div 5$ (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 :)
