Which of the following is another way to express the equation 16 = - 9 + z?

Since you didn't give the options, we'll answer In steps and you can pick which step you have as an answer choice ...

16 = - 9 + z

Add 9 to each side for

16 + 9 = z (that's one option)

Add like terms for

25 = z (there's another)

You could also go a whole different route and take the original equation

16 = - 9 + z

subtract z from each side for

16 - z = - 9

Any of those would be another way to express the equation.
