You group all like terms together so it would be
-5x+5x-3y+y-9z+8z
-5x+5x that = 0
-3y+y=-2y
-9z+8z=-z
So you bring it all together and you have
-z-2y

The numbers with the same numbers can be added together for example the -5x and the 5x in your problem can be added together for a result of 0, the lone y in your problem would become 1y added with your other -3y would equal -2y. In the end your answer would look something like this -2y-z

Group the terms with similar variables, like this:
-5x+5x-3y+y-9z+8z
Then simplify.
-2y-z

You must mean simplifying the expression.
-5x+y+8z+5x-3y-9z...collect like terms
y+8z-3y-9z...-5x+5x=0
-2y-z.....1y-3y=-2y...and...8z-9z= -1z or -z

You first add like terms:
-5x, 5X ----= 0x
y, -3y-----= -2y
8z, -9z----= -1z
there for: 0x-2y-1z= -2y-z
I think the person above me was multipying factors

Solution:
-2y-z
2006-06-14 10:23:29 · answer #6 · answered by Nacho 2 · 0⤊ 0⤋
since x y z are arbitary constants
hence the sol is -2y-z (simple addition and subtraction of known components

-5x+y+8z+5x-3y-9z
-5x+5x+y-3y+8z-9z
-5x+5x+5x+y-3y+8z-9z
ans: 5x-3y-1z

Depends what answer you're looking for...
If you're looking to evaluate x, y, or z, you need the equation to equal some constant
