03 Simultaneous Equations
When , the solution to the simultaneous equation:
is given by the formula:
Program
Ｌｂｌ １：？→ Ａ：？→ Ｂ：？→ Ｃ：Ａ → Ｙ：Ｂ → Ｘ：Ｃ → Ｍ：？→ Ａ：？→ Ｂ：？→
Ｃ：ＡＸ － ＢＹ → Ｄ：Ｄ ＝０⇒ Ｇｏｔｏ １：（ＸＣ － ＢＭ）÷ Ｄ → Ｘ：（ＡＭ － ＣＹ）÷
Ｄ→Ｙ：Ｘ Ｙ ＜ 81 STEP ＞
INPUT Ａ,Ｂ,Ｃ (first time): Ａ,Ｂ,Ｃ (second time):
OUTPUT X,Y: solutions to the simultaneous equation
