Answer:
-1 1/3
Step-by-step explanation:
To find the mean, add up all the numbers
(-4+-3+-1+-1+0+1) =
-8
Then divide by the number of terms
-8/6
-4/3
-1 1/3
I think your suppose to combine like terms to find your answer.... Like for example 5x+2=6x+11
what I did first was combine my x's which is 5x+6x is 11x
then I added 2+11 and that gave me 13 so I put it together and got 11x+13
