Question

Add 2x+3y+z and 2x-y-z 

Answer 1

We have:

2x + 3y + z and 2x - y - z

We have to add 2x + 3y + z and 2x - y - z.

Solution:

$\therefore$ (2x + 3y + z) + (2x - y - z)

= (2x + 2x) + (3y - y) + (z + z)

= 4x + 2y + 2z

Taking 2 as common, we get:

2(2x + y + z)

$\therefore$ (2x + 3y + z) + (2x - y - z) = 2(2x + y + z)

Hence, the addition of 2x + 3y + z and 2x - y - z is "2(2x + y + z)".

Answer 2

SOLUTION

TO DETERMINE

Add

$\sf{(2x + 3y + z) \: \: and \: \: (2x - y - z)}$

EVALUATION

Here the given given two expressions are

$\sf{(2x + 3y + z) \: \: and \: \: (2x - y - z)}$

Adding we get

$\sf{(2x + 3y + z) + (2x - y - z)}$

$\sf{ = 2x + 3y + z+ 2x - y - z}$

$\sf{ = 2x + 2x + 3y - y + z- z}$

$\sf{ = 4x + 2y }$
