c= 5i+2j d=-2i-4j find u if c+ud is parellel to vector i. I know the parallel bit is important but I don't know how. Would it be possible for you to explain to me how? Also its my first time here, hi

Also its my first time here, hi a vector parallel to the unit vector i will have zero for a j component. (5i + 2j) + u(-2i - 4j) = ai + bj what value of the scalar u will yield the vector ai + bj such that b = 0?
