|x−y+z|, if x=3; y=−2; z=−6
Finger [1]

Answer:

1

Step-by-step explanation:

Try the question without the absolute value brackets first.

Then it would be 3+2-6

Since it states "x-y" and y is -2, then it would be 3+2 since a negative times a negative becomes a positive

Same thing for "z", instead of +6 it would be -6 because a negative times a positive is still a negative

Now, 3+2-6 is -1 but MAKE SURE to put the absolute value brackets back. Making the answer a positive number. Therefore, it would be 1
