At this page you will learn about solving equations by linear combination. Here is an example of one problem You could solve by linear combination: |
|
5x-2y=4 2(3x+y=9) 6x+2y=18 11x=22 x=2 3(2)-2y=4
|
here are the two
equations.
You have to multiply the second equastion by two so the "Y"'s will cancel out and you can solve for "x", and that equals: you have to put the x back
in the first equastion ad solve for y.
