Question 225309: Could you please walk me through the steps writing the linear system into a matrix equation. x+y=5 , 3x-4y=8
Answer by jsmallt9(3758)   (Show Source):
You can put this solution on YOUR website! - Get the equations into "standard" form: Ax + By = C. Your first equation is already in this form. All we need to do with the second is to rewrite it as an addition:
3x + (-4y) = 8 - Then just write the numbers into a matrix, leaving out all the "punctuation" (addition, =, parentheses, etc.):
+- -+
| 1 1 5 |
| 3 -4 8 |
+- -+
(I apologize for the crude matrix "corners".)
