Could someone please help me with this problem?
Solve using the multiplication principle. Don't forget to check.
z=35.
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.
