LINEAR EQUATIONS SOLVER

Linear Equation:
Ax + B = C has a general symbolic solution:
x= (CB)/A.
Special cases: if
C=
0,
x= B/A;
if
A=
0 there is no solution (
x=infinity).
Usage.To solve the Linear equation enter the numbers for A, B,
C in corresponding Text Boxes and click on the [=] Button. 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.
Useful Tips.Equation
Ax  B = C is an
equivalent to
Ax +(B) = C, so in order to solve this equation
enter the negative value B in a corresponding Text Box.
Example: Let's consider the equiation
3x  5 = 4,
which is an equalent to
3x + (5) =4, so negative number 5
must be entered in corresponding Text Box
B.
