so lets write this equation out. Let x be that number we are trying to find.

So five-sevenths is a fraction that is written like this

5/7

when you see the word "of" that means multiplication

so we can write the full equation.

(5/7)x = -35

now we can solve

Multiply both sides by 7

5x = -245

now divide by 5
and we get

x = -49
