5 = –(–z + 3)

A.
–8

B.
8

C.
–2

D.
2

Answer 1

im guessing this one is -2..

Answer 2

This one is a bit more tricky than your last one, with the (-z + 3) in parentheses... you must first distribute your - to each one inside, as it is basically -1 x -z and -1 x 3

Answer 3

or plug in the numbers...

Answer 4

So that'll get you z - 3

Answer 5

Then just like last time, isolate your variable, add 3 to each side.

Answer 6

5=(-2+3)?

Answer 7

5 + 3 = z - 3 + 3

Answer 8

oh yeah

Answer 9

You know -3 + 3 is 0 so, z = 5 + 3

Answer 10

8?

Answer 11

Yes :)

Answer 12

And as she was saying, you can check your answer after solving by plugging it into your variable.
