# How can I represent a system of many equations? Is it possible?

Jun 9, 2015

Yes, it is possible.

#### Explanation:

Here's how that would look

• Without the hashtags

{ (2x + 4y -z = 7), (x -y + 5z = 10), (-x + 3y + 3z = 25) :}

• With the hashtags

$\left\{\begin{matrix}2 x + 4 y - z = 7 \\ x - y + 5 z = 10 \\ - x + 3 y + 3 z = 25\end{matrix}\right.$

You can add as many equations as you like, as long as you group them like that.

If you want the bracket to be on the other side of the equations, you can write

• Without the hashtags

{: (2x + 4y -z = 7), (x -y + 5z = 10), (-x + 3y + 3z = 25) :}}

• With the hashtags

{: (2x + 4y -z = 7), (x -y + 5z = 10), (-x + 3y + 3z = 25) :}}
