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).

LINEAR EQUATIONS SOLVER
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:
If Text Box A is left empty, system will automatically
assign 1 to A, so the Equation will become x + B = C.
If Text Box B is left empty, system will assign 0 to it,
thus the Equation will become: Ax = C.
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.
