i dont get it

Let's say we have a number $$n$$. Double it to make $$2n$$. Divide it by three to make $$\frac23n$$. Subtract $$3.1$$ to make $$\frac23n-3.1$$. Finally, divide by $$5$$ to make $$3.7$$, so$\frac{\frac23n-3.1}{5}=3.7$Solve for the original number $$n$$.

What answer did you get? Plug it in for $$n$$ and see if your results are right.
