2z + 12y - 32

1) 2z cannot be combined with any other number because no other number has the variable z.
2) 4y and 8y are both positive and van be combined. Therefore, it is 12y.
3) -32 cannot be combined with any other number because it doesn't have a variable that is the same as the others.
Therefore, the answer is 2z + 12y - 32
