Solving Systems Using Elimination
... Now you have “eliminated” the y term and have a one-variable equation to solve. 8x = 16 So, x = 2 You have the first half of your ordered pair. Plug in 2 for x in one of the equations to find y. 5(2) – 6y = -32 ...

2 Matrices and systems of linear equations
... We proceed in more or less the same manner as above - that is, we try to eliminate x from the second equation, and y from the first by doing simple operations on the matrix. B efore we start, observe that each time we do such an ”operation”, we are, in effect, replacing the original system of equati ...
