Question

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

Answer 1

Explanation:

Add 7 to both sides

9x = 0

Then divide by 9 both sides to get x by itself

x = 0

Answer 2

Add 7 to both sides

Explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol
