Question

-9x+3z-8y-x+12y+z-z+5y-11x

Answer 1

-21x + 9y + 3z

Answer 2

-21x+9y+3z
-3(7x-3y-z)

Answer 3

We have
\[-9x+3z-8y-x+12y+z-z+5y-11x\]
Let's bring the like terms together
\[-9x-x-11x-8y+12y+5y+3z+z-z\]
\[x(-9-1-11)+y(-8+12+5)+z(3+1-1)\]
now simplifying
\[x(-21)+y(9)+z(3)\]
we get
\[-21x+9y+3z\]
we can take a 3 out from each of the terms
\[3(-7x+3y+z)\]

Answer 4

ok so thats the final answer

Answer 5

yeah nee nee

Answer 6

is says it wrong

Answer 7

nee you can also write like this
\[-3(7x-3y-z)\]

Answer 8

Try -21x + 9y + 3z

No instructions were given with the problem. However, I doubt you were expected to factor out the three.
