WebTo solve an equation like this, it is useful to think of the matrices as variables. So in this case, we have an equation along the lines of B-A=C with A representing the first matrix and the second one being represented by C. The goal of this is to isolate B and we accomplish this by adding A to both sides, leaving us with B=C+A.
