Simplify the expression: (3 + z) + –9 = _____

Write Down Given Expression: First, let's write down what we got: (3 + z) + –9. We gotta combine like terms, so let's put the numbers together and keep the z where it is. So it's like 3 + z - 9.Combine Like Terms: Now, we do the simple math with the numbers. 3 - 9 is -6, right? So we got z + -6, which is the same as z - 6.Perform Simple Math: Oops, we're done! That was quick. So the simplified expression is z - 6. No more steps needed.
