USAGE
Enter coefficients in input boxes - it could be any combination of Decimals, Fractions and Mixed Numbers,
positive or negative, then click on [SOLVE] button to get a solution for X, Y as Fractions and equivalent Decimals.
Following rules apply:
-
If any of A1, A2, B1, or B2 are empty, system will assign 1
-
If any of C1 or C2 are empty, system will assign 0
ABSTRACT
A1X + B1Y=C1
A2X + B2Y=C2
has a solution using Determinant (Det)
Det= A1B2-A2B1
X = (B2C1 - B1C2)/Det
y = (A1C2 - A2C1)/Det
If Det=0 there is no solution.
If C1=C2=0 then trivial solution: X = Y = 0.
