Use unit vectors to express the vector C, where C = 3.00A - 4.00B

Keep in mind that C, A, and B are vectors, I could not get the Latex to work.

2. Relevant equations

There are no relevant equations, but I don't know if the question above the one I am asking refers to this, as I got that:

Vector A = 1.23 i + 3.38j

Vector B = -2.08i - 1.2j

3. The attempt at a solution

My attempt would be to subtract -2.08 from 1.23 leading the final i to be 3.31 (as it's subtracting and negative with negative = +.) and the final j to be 4.58.

If this is how it is suppose to go, then do I plug those numbers in for A and B, multiply time their coeffiecients

ex: 3.00 (3.31) - 4.00 (4.58) = C ?
