$- 35 x$

Explanation:

We are not given a sign for the 7 so by convention it is positive.

Write as $\left(- 5\right) \times \left(+ 7\right) \times x$

When multiplying or dividing, if the signs are different than the answer is negative. If they are the same the answer is positive.

We are not given any sign for the $x$ so by convention it is positive

$\text{Just the numbers} \to \left(- 5\right) \times \left(+ 7\right) = - 35$

$\text{Combine with the } x \to \left(- 35\right) \times \left(+ x\right) = - 35 x$
