Using elimination to solve the system 2x + y = 8 and x + y = 4, which of the following could be the first step? (Points : 2) 2x + y = 8--------> 2x + y = 8 (x + y = 4)(-1)---> -x - y = -4 2x + (4 - x) = 8 2x + y = x + y 3x + 2y = 12 x = 4
is it just me or you have the answer already?
its what step is next that is correct
I see nothing wrong in the procedure sequence :|
jdoe. u have to figure out the next step....
ahemm, I guess I didn't get it firstly :|, well, multiplying by (-1) on the second equation pretty much solves it
