Solving built-in Equation
The built-in equations are: “2*2 lin. solve” (Ax+By=C, Dx+Ey=F) and “3*3 lin.
Solve”(Ax+By+Cz=D, Ex+Fy+Gz=H, Ix+Jy+Kz=L). If you select one of them, the
,
and
key will have no effect. Pressing the
will
request 6 variables (A to F) for the 2*2 case or 12 variables (A to L) for the 3*3
case, and use them to find x, y for a 2*2 linear equation system or x, y and z for a
3*3 linear equation system. The result will be saved in variables x, y, and z. The
calculator can detect cases with infinitely many solutions or no solutions.
Example: solve the x,y in simultaneous equations
