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.
