In this section, you will learn how to solve linear equations by using the `linalg.solve()` method. When you have a linear equation to solve, as in the form , in simple cases you can just calculate the inverse of *A* and then multiply it by *B* to get the solution, but when *A* has a high dimensionality, that makes it very hard computationally to calculate the inverse of *A*. Let's start with an example of three linear equations with three unknowns, as follows:

So, these equations can be formalized as follows with matrices: ...
