# Solving Simultaneous Equations Using the TI-89

To demonstrate the solution of matrices using the TI-89
Titanium we will solve the following

equations.

3x + 4y = 1 Note: The solution is: x = 0.714 and y =
-0.286

2x – 2y = 2

This set of equations can be solved using the simultaneous
equations solver. First we need to go

to the simultaneous equations solver in the apps menu as shown.

Press Enter and select New.

Because this is problem involves two equations with two
unknowns we need to enter this

information in the screen shown.

After pressing enter we need to enter the equations as shown.
