Question

This is an equation.

Answer 1

Let's evaluate left side first.

There are 4 -5's and 5 -3's

So that's 4(-5) + 5(-3) = -35

So now our equation is -35 = -5x

Now divide both sides by -5:

-35 / -5 = x

7 = x

So the missing number would be 7 to make this equation true.

Final answer: 7

Hope this helps.
