Generally, its ok to write system of equations in latex. But i don't have any idea how can I place the dots like what you see in the picture attached.

Any help would be greatly appreciated.

Thanks in advance.

Something like this?
[tex]\begin{align*}
y_1 a_{11} & + & y_2 a_{21} & + & \cdots & + & e_1 & = & 0 \\
y_1 a_{12} & + & y_2 a_{22} & + & \cdots & + & e_2 & = & 0 \\
\vdots & & \vdots & & & & \vdots& & \\
y_1 a_{1M} & + & y_2 a_{2M} & + & \cdots & + & e_M & = & 0 \\
\end{align*}[/tex]

FAQ: How do I write a system of equations with dots in latex?

What is the syntax for writing a system of equations in LaTeX?

The syntax for writing a system of equations in LaTeX involves using the "align" environment, which is accessed by including the "amsmath" package in the preamble of the document. The equations are then written using the "&" symbol to indicate alignment points and the "\\" command to start a new line.

How do I label and reference individual equations within a system in LaTeX?

To label and reference individual equations within a system in LaTeX, the "align" environment can be used in conjunction with the "\label" and "\ref" commands. The label should be placed after the equation and the reference can be used within the text to refer to the equation number.

Can I use different types of brackets or parentheses in a system of equations in LaTeX?

Yes, you can use different types of brackets or parentheses in a system of equations in LaTeX by using the "\left" and "\right" commands. These commands automatically adjust the size of the brackets or parentheses based on the content within them.

How can I align the equal signs in a system of equations in LaTeX?

The equal signs in a system of equations can be aligned by using the "&=" symbol instead of just "=" in the "align" environment. This will ensure that all equal signs are aligned in a single column.

Is there a way to add comments or notes to a system of equations in LaTeX?

Yes, comments or notes can be added to a system of equations in LaTeX using the "\intertext" command within the "align" environment. This command allows for text to be inserted in between equations without disrupting the alignment.
