 To use, enter an equation in each field. The number of equations MUST be the same as that of the variables. e.g if the variables are only x1 & x2, the number of equations will be two. For m Equations & n variables with a representing the coefficients & b the constants, we have an11X1+an12X2=b1, where an11 & an12 are the coefficients of X1 & X2 respectively & b1 is a constant for equation 1 & an21X1+an22X2=b2 are the coefficients & constant for equation 2. The coefficients can be placed just before the unknowns as shown in algebra text books e.g 2x1+4x2-8x3=21 . . . instead of having to use the multiplication operator * as in 2*x1-4*x2 . . . .

If you require the ability to SOLVE not only linear equations as in the above calculation but to SOLVE systems of non-linear equations (both algebraically and graphically such as: (x-2)^2+(y-2)^2=4       2y=x^2-4x+4   plus many more capabilities including Programming ,  click on the above link 'virtual handheld computers/calculators, to view examples of their power.
