$$\frac{13}{x} - 7x$$
To translate this statement into an expression, we need to break down the different parts of the statement: The "quotient of $13$ and a number" means $13$ is divided by a number, $x$. "Decreased by $7$ times a number" means to subtract $7$ times that same number, $x$. Putting all these parts together, we have: $$\frac{13}{x} - 7x$$
