Respuesta :

Let plug the variable into the equation.

[tex]x = 5[/tex]
[tex]5/3=15[/tex]

We can conclude that this is incorrect because [tex]5/3[/tex] does NOT equal [tex]15[/tex]

The correct answer would be: [tex]15/3 = 5[/tex]; [tex]15/5=3[/tex]; or
 [tex]3(5) = 15[/tex] or [tex]45/3=15[/tex]

All [tex]4[/tex] of these are correct answers.

Input the answer the student obtained:
x/3=15
x=5
5/3=15
5/3
=1.6667
1.6667≠15

The Correct Answer:
Solve for x.
x/3=15
Multiply both sides by 3.
(x/3)*3=(15)*3
x=45

To check, input the answer in the equation:
45/3=15
15=15

The answer would be 15.

Hope this helps.
