How to insert an equation with a system of linear equations or linear system
How to add an equation in your document, see Working with Microsoft Equation.
To insert a system of linear equations, do the following:
In the Professional format:
1. In your own equation, enter f (x)=.
2. Under Equation Tools, on the Design tab, in the Structures group, click the Bracket button:

In the Bracket list, under Cases and Stacks, choose Cases (Two Conditions):
![Superscript in equations Word 2016 Superscript in equations Word 2016](/images/tips/equation2016/cases_two.png)
3. In every box, enter the appropriate formula, for example:
![A system of linear equations or linear system in Word 2016 A system of linear equations or linear system in Word 2016](/images/tips/529/1.png)
To insert a new line for this system of linear equations, just click Enter:
![A new line for the system of linear equations or linear system in Word 2016 A new line for the system of linear equations or linear system in Word 2016](/images/tips/529/3.png)
In the Linear format:
1. In your own equation, enter f (x) = {.
2. Enter \eqarray to start a system of linear equations. Then you enter a space key, this linear formula transformed to the professional format:
![A system of linear equations or linear system 1 in Word 2016 A system of linear equations or linear system 1 in Word 2016](/images/tips/529/4.png)
3. In the brackets, enter formulas with symbols @ that divide rows in the linear system:
![A system of linear equations or linear system 2 in Word 2016 A system of linear equations or linear system 2 in Word 2016](/images/tips/529/5.png)
4. Enter \close to end the system of linear equations:
![A system of linear equations or linear system 3 in Word 2016 A system of linear equations or linear system 3 in Word 2016](/images/tips/529/6.png)
Then you enter a space key, the formula transformed to the professional format:
![A system of linear equations or linear system in Word 2016 A system of linear equations or linear system in Word 2016](/images/tips/529/2.png)
