Given that c=3i+4j and d=i-2j find:
S if c-sd is parallel to 2i + j
What I don't understand is why do we make them equal to each other

Two vectors are parallel if one is a scalar multiple of the other. In this case you are looking for the value of s for which (c - sd) is a scalar multiple of (2i + j).
