3.2 Systems mult­add method
For the following systems, you will not be able to add down like we have been doing since nothing will cancel out. This is where the Multiplication/Addition Method comes in:
wksht #4
2x­3y = 12
x­4y = 1
wksht #6
x ­ y = 2
4x­3y = 11
3.2 Systems mult­add method
wksth #7
­2x+3y = 14
x+2y = 7
wksth #12
2x­ y = 16
­x+2y = ­8
