W + X + Y + Z = 2
W + 2X + 2Y + 4Z = 1
W - X + Y + Z = 6
W - 3X - Y + Z = 2
I need to know what numbers represent the variables above. Please explain in as detailed a way as possible, how you arrived at the numbers, whether by using a calculator, or by hand. I have a TI-86, so if you are familiar with that calc, please tell me how to solve this, in as detailed a manner as possible, using a 4 x 4 matrix.
I am more or less an Algebra newb, so please don't be afraid to break this down into as simple a form as possible. Thanks.
