I have no idea what is the first step in the question. Please solve it for me. Following is the question relating to the chapter i.e. Vectors in two dimensions:

{1} If a= (p+q p), b= (3 q+1) and a=b, find the values of p and q.
NB: The bracket of a and b represents column vector.
I will be highly obliged if you answered my question.

If your vectors are orthogonal, then each dimentsion must equal each other.
p=3q and qp=1
