Step 3. Change into the HOME view and enter
the calculation M1

*M2. The result is
the (x,y) coordinate of the solution.
A similar method can be used to
solve the second 3x3 system of
equations.
Third method - using the 3x3 Solver aplet
This method uses an aplet which is available
from the internet called the “Simult 3x3”.
It allows easy solution of 2x2 and 3x3 systems
of linear equations in a format which is more
user friendly than the use of matrices for
student who are not familiar with them.
