268 Linear Solver app

Note

If the last time you used the Linear Solver app you solved

for two equations, the two-equation input form is

displayed. To solve a three-equation set, tap ; now

the input form displays three equations.

Define and solve

the equations

2. You define the equations you want to solve by

entering the coefficients of each variable in each

equation and the constant term. Notice that the cursor

is positioned immediately to the left of x in the first

equation, ready for you to insert the coefficient of x

(6). Enter the coefficient and either tap or

press

3. The cursor moves to the next coefficient. Enter that co-

efficient and either tap or press

Continue doing likewise until you have defined all the

equations.

Once you have

entered enough

values for the

solver to be able

to generate

solutions, those

solutions appear

near the bottom

of the display. In

this example, the solver was able to find solutions for

x, y, and z as soon as the first coefficient of the last

equation was entered.

As you enter

each of the

remaining known

values, the

solution changes.

The graphic at

the right shows

the final solution

once all the

coefficients and constants had been entered.
