How to insert an equation with a system of linear equations or linear system

Word 365
This tip shows how to add an equation with a system of linear equations (or linear system) – a collection of two or more linear equations involving the same set of variables.

How to add an equation in your document, see Working with Microsoft Equation.

To insert a system of linear equations, do the following:
