k EQUA — Recalling Equation Coefficients and Solutions
Selecting {EQUA} from the VARS menu displays the equation coefficient and
solution recall menu.
•{S-Rlt}/{S-Cof} ... matrix of {solutions}/{coefficients} for linear equations with
two through six unknowns
•{P-Rlt}/{P-Cof} ... matrix of {solution}/{coefficients} for a quadratic or cubic
equation
Example 1 To recall the solutions for the following linear equations with two
unknowns
