Question

x-3y +4z , y -2x -8z ,5x -2y -3z ​

Answer 1

Answer:

The answer is 4x+2y-7z

Step-by-step explanation:

x-2x+5x= 4x

3y+y-2y= 2y

4z-8z-3z= -7z

Answer 2

Answer:

Required sum,

=(x−3y+4z)+(y−2x−8z)+(5x−2y−3z)

Collecting like terms,

−x−2x+5x−3y+y−2y+4z−8z−3z

Adding like terms,

=(1−2+5)x+(−3+1−2)y+(4−8−3)z

=4x−4y−7z
