Entering And Solving A Problem - Texas Instruments TI-83 Plus Manual Book

Entering and Solving a Problem

To solve a system of equations, you enter the number of
equations, the number of unknowns, and then you enter the
augmented matrix (one that contains the coefficients as well as
the constants) of the system.
Note The Simultaneous Equation Solver application does not find
solutions to complex systems. The augmented matrix can only
contain real numbers.
The following example solves this system of equations:
x + y + z = 5
2x .5y + z = 10
x 2y + 3z = 15
