This app works on any combination of Decimals, Fractions and Mixed Numbers. First, select either Fractions or Decimals calculation mode, then enter the coefficients (A, B, C) in corresponding input boxes and click on [SOLVE] to get a solution. The following rules apply:
  1. If Text Box A is left empty, system will automatically assign 1 to A, so the Equation will become x + B = C.
  2. If Text Box B is left empty, system will assign 0 to it, thus the Equation will become: Ax = C.
  3. Text Box C must always contain a valid number; otherwise the System will generate an error message.
In order to solve the equation Ax - B = C consider entering it as Ax +(-B) = C; e.g. for 3x - 5 = 4 enter negative number -5 in second Text Box.

LINEAR EQUATIONS

Linear Equation: Ax + B = C has a general solution: x= (C-B)/A
Special cases: if C=0, x= -B/A;  if A=0 there is no solution (x=infinity).
