@navk please help

Answer 3

First combine the like terms and then add them. do you know what the like terms are

Answer 4

yeah,i know what they are @navk

Answer 5

so for example you would first combine the x terms to get 8x - 4x = 4x

then combine the y , z and constant terms similarly

Answer 6

so would it be 7y and 7x? @navk

Answer 7

no how did you get that can you show your work

Answer 8

i just added them together

Answer 9

2y-5y= -3y right and then 3z +4z=7z @navk

Answer 10

Great! That is correct except that the 3x has a negative sign on it.

Answer 11

so do i take off the negative sign or does it stay there? @navk

Answer 12

You can't change the question itself! Or are you talking about the answer, because in it there is no negative sign to take off! You need to put a negative sign before the 3z

Answer 13

it's 8x-4x+2y-5y-3z+4z-4+6
=4x-3y+z+2
