Write or type a set of brackets with a space between the brackets. The space depends on how large your matrix will be. The brackets used in matrix notation look like this:
[ ]
Insert the coefficients of the x and y variables in between the brackets. For example, consider two lines with the following equations:
2x + 2y = 4 and 3x + 4y = 6
You would write 2 and 2 on the top line between the brackets and 3 and 4 on the second line.
Write a set of parentheses to the right of the brackets. Parentheses look like this:
( ).
Write an x on the upper portion between the parentheses and a y underneath the x.
Write an equal sign (=) to the right of the parentheses.
Write a second set of parentheses on the right of the equal sign Insert the numbers without variables from the equations. In this case, you would write a 4 in the upper portion of the parentheses and a 6 underneath the 4.
