Question

I don't understand help​

Answer 1

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

Answer 2

Answer:

$x= 15$

Step-by-step explanation:

Francisca's mistake was that when she had an equation $5 = \frac{1}{3} x$ instead of dividing both sides by  $\frac{1}{3}$  she substracted  $\frac{1}{3}$  from both sides. So the correct way would be...

$5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)$

$15 = x$
