Finally the rare (unobtainable) manual for Sharp EL-506P

3x + y = 15
x + 2y = 10

EL-506A: Error
EL-546: x=4, y=3 Det=5

The way the 3-VLE mode works is you enter the coefficients in sequence:
A1 -> B1 -> C1 -> D1
A2 -> B2 -> C2 -> D2
A3 -> B3 -> C3 -> D3
x -> y -> z -> Determinant

For the 2-variable linear equation I left C1, C2, A3, B3, C3, D3 all set to zero:
3 -> 1 -> 0 -> 15
1 -> 2 -> 0 -> 10
0 -> 0 -> 0 -> 0
4 -> 3 -> S -> 5 (S = Skipped, the EL-546 skips this since it's a 2 Variable equation)

Could you solve it by setting C1=0, C2=0, A3=0, B3=0, C3=1, D3=1 ?
