Question

Add the following :

$$\begin{gathered} 2x-3y+4z \\ 3x+y-z \\ -x-y-2z \\ \overline{} \end{gathered}$$

Answer 1

On adding the given terms we get,

$$\begin{gathered} 2x-3y+4z \\ 3x+y-z \\ -x-y-2z \\ \overline{\underline{4x-3y+z}} \end{gathered}$$

Hence, $4x-3y+z$ is the required answer.
