Question

I don't understand help​

Answer 1

`x= 15`

Explanation:

Francisca's mistake was that when she had an equation
`5 = (1)/(3) x` instead of dividing both sides by
`(1)/(3)` she substracted
`(1)/(3)` from both sides. So the correct way would be...

`5 = (1)/(3) x\\\\(5)(3) = ((1)/(3) x )(3)`

`15 = x`

Answer 2

They subtracted 1/3 from both sides instead of dividing 1/3 from both sides
