This java applet solves linear equations of two unknown variables. You have to take care of two points, while using this applet. First, you should only enter numbers only as coefficients. You can not use fractions or other expressions as coefficients. If your equations have fractions as coefficients, reduce them to decimal equivalents before entering them in the text boxes. For example, if your Equation is like this:
2/5 x + 3/4 y = 27
then reduce it to :
0.4 x + 0.75 y = 27
Secondly, if any of the expressions has a Negative sign, then make the sign of the coefficient negative. For example, if the equation is like this:
2/5 x - 3/4 y = 27
then enter "-0.75" (without quotes) as coefficient of y in the Text Box.
