This week's problem comes from the equation category.

How would you solve \(\frac{4(\frac{u}{5}+2)}{4}=\frac{14}{5}\)?

Let's begin!



\[\frac{4(\frac{u}{5}+2)}{4}=\frac{14}{5}\]

1
Cancel \(4\).
\[\frac{u}{5}+2=\frac{14}{5}\]

2
Subtract \(2\) from both sides.
\[\frac{u}{5}=\frac{14}{5}-2\]

3
Simplify  \(\frac{14}{5}-2\)  to  \(\frac{4}{5}\).
\[\frac{u}{5}=\frac{4}{5}\]

4
Multiply both sides by \(5\).
\[u=\frac{4}{5}\times 5\]

5
Cancel \(5\).
\[u=4\]
