Directions:

Enter each linear equation in a separate line, in the form:
c1x + c2x + c3x + c4x .... cNvx= C
where:

• "x" can be any character value "a" through "z".
• "c1" through "cN" are coefficients to each term, and must be represented by a digit, (numerical decimal and floating point values only).
• The maximum number of distinct terms, "N", is 26.
• The left and right sides of each equations must be separated by an "=" symbol preceded and succeded by a single space.
• Each term must be separated by a space followed by a "+" or "-" sign followed by a space.
• Negative terms are denoted by a "-" symbol in front of them.
• If you need to enter in a fractional coefficient "c", use the closest approximating decimal.
• The terms do not necessarily have to be in alphabetical order.
• Any single constant not associated with a variable will simply be added to the right hand side of the equation by the preprocessing algorithm.
  
• You may include more than one term with the same variable character. For example, you can have the terms "5d" and "2.3d" in the same equation. Such duplicate terms will simply be added together by the preprocessing algorithm.
• The right side of each equation must be a numerical floating or integer constant.
