This lesson will assist student in learning to solve simple linear systems of equations in two variables by elimination. The graphical solution is demonstrated as well.[br]The process is completed by manipulating the sliders to multiply or divide the coefficient to get either the x or y values to be the same (opposite).[br][br]n and m are values from 1-10, r and s multiply the line by -1, and i and j turn the n and m values into divisors.

Enjoy learning linear combinations interactively.
