Solves system of equa
tions and displays X.
Displays Y.
Displays Z.
Description:
Multiplies X by 23.
Multiplies Y by 15.
Adds the last two
results.
Multiplies Z by 17.
Completes the left side
of the equation. Since
the left and right sides
are both equal to one
(to 11 significant dig
its), the solution is
correct.
