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

  • Algebra -

    Multply both sides of the equation by
    -1 to get an equation for z.

  • Algebra -

    So then I would set the problem up like this: -1*-z=35*-1. z=-35.
    Is this correct?

  • Algebra -

    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.
