Answer:
-7
Step-by-step explanation:
First, we know that we are solving for x so what we need to do is to find out what times -5=35.

So we know our answer cant be positive 7, which means we need the opposite of 7 which is -7.
And:
-5x-7=35
This makes the equation true:
Hence, the correct answer is -7
