Hey!
(a)
(b)
Multiply second equation by -9.
(a)
(b)
Add the two equations.
.
Can you do the rest?
Okay, I am stuck on linear equations again. I am not understanding what to do with the fractions? I have read my text and our online lecture but obviously something isn't sinking in. The two equations that I am stuck on is as follows:
1. -3x + 6y = 2
2x + (2/3) y = 1
2. (x/3) + (y/4) = 7
(x/4) + (y/3) = 7
Looking at #2, one can see that the answer is 12 but I am not clear on how it should be written.
For # 1 what do I do with the 2/3?
Thanks in advance for the help
