OpenStudy (phi):
you should first try to find where the first two lines meet: y=-x+1 2x-y=2 one way is replace the y in the second equation with (-x+1), like this: 2x - (-x+1)= 2 can you "solve for x" ?
OpenStudy (sugarmochi):
would x = 1/4 ?
OpenStudy (phi):
can you show your work? 2x - (-x+1)= 2 becomes 2x +x -1 = 2 now what ?
