kEQUA — 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

2x + 3y = 8

3x + 5y = 14

1(S-Rlt)w

Example 2 To recall the coefficients for the following linear equations with three unknowns

4x + y – 2z = –1 x + 6y + 3z = 1

–5x+ 4y + z = –7

2(S-Cof)w

Example 3 To recall the solutions for the following quadratic equation

2x2 + x – 10 = 0

3(P-Rlt)w

Example 4 To recall the coefficients for the following quadratic equation

2x2 + x – 10 = 0
