Find the values of x, y and z so that the vectors ` vec a=x hat i+2 hat j+z hat k`and ` vec b=2 hat i+y hat j+ hat k`are equal.

Explanation

To find the values of \( x \), \( y \), and \( z \) such that the vectors \( \vec{a} = x \hat{i} + 2 \hat{j} + z \hat{k} \) and \( \vec{b} = 2 \hat{i} + y \hat{j} + \hat{k} \) are equal, we can set the corresponding components of the vectors equal to each other.

### Step-by-Step Solution:

1. **Write down the vectors:**
\[ \vec{a} = x \hat{i} + 2 \hat{j} + z \hat{k} \]
