Could someone please help me with this problem?
Solve using the multiplication principle. Don't forget to check.
The solution is z=
Multply both sides of the equation by
-1 to get an equation for z.
So then I would set the problem up like this: -1*-z=35*-1. z=-35.
Is this correct?
Yes, if they insist on your showing the (-1)* step. Usually that kind of thing is omitted when solving equations. It is rather obvious what is going on.
