#### Question

If `veca=xhati+2hatj-zhatk and vecb=3hati-yhatj+hatk` are two equal vectors ,then write the value of x+y+z

#### Solution

Given `veca=xhati+2hatj-zhatk and vecb=3hati-yhatj+hatk` are two equal vectors

`therefore xhati+2hatj-zhatk=3hati-yhatj+hatk`

x=3,y=-2,z=-1

x+y+z=3+(-2)+(-1)=0

Therefore, the value of *x* + *y* + *z* is 0.

Is there an error in this question or solution?
