Answer:

Explanation:
Given vectors:



When subtracting vectors, we subtract the elements in the same position from one vector from the elements in the same position of the other vector. Therefore, subtracting vector b from vector c gives:

When multiplying a vector by a constant, we multiply each component of the vector by that constant. Therefore, multiplying vector a by 3 gives:


Multiply (c - b) by 1/4:


Finally, subtract the vectors:
