(12C) Simultaneous Equation in Two Unknowns - Gamo - 10-12-2024 07:31 AM
This program is adapted from
HP-33E Mathematics Applications Handbook
On Page 16 "Algebra and Number Theory"
Original program use "Storage Register" R1 to R6
And with that it takes more time to input all the data.
With this version I will use the TVM buttons but
TVM buttons only have 5 registers to store it on
[n] [i] [PV] [PMT] and [FV] the 6th register will be on R1
-----------------------------------------------------------------
Example Usage:
5X - 3Y = 12
2X + Y = 9
Input Data from left to right start from top equation downward.
5 [n] 3 [CHS] [i] 12 [PV] 2 [PMT] 1 [FV] 9 [R/S] display X = 3.5455
[R/S] Y = 1.9091
Remark: to review answer of X and Y use [X<>Y] to review answer
