Well, look at either equation and try to solve for both variables. The best you can do is to write one in terms of the other, but you will never be able to determine what each variable is unless you have a second equation. Because there are two unknowns, we need two equations. However, any method of solving systems of equations will fail in ... Solving equations with matrices is very similar to solving an equation with real numbers. Just like real numbers, we can add or subtract the same matrix on both sides of an equation to isolate the variable matrix. The big change is that we cannot divide by a matrix - division by a matrix is not defined.
