how do you rearrange this problem?
(i) 2x+%2B+y+%2B+1+=+0
(ii) x+%2B+3y+%2B+3+=+0+
solve (i) for y as
(iii) y+=+-2x+-+1
solve (ii) for y as
(iv) y+=+%28-1%2F3%29x+-+1
Now if you are to solve for x and y, we get
(0,-1)
-----
and this one to?
(i) 2x+-+y+-+8+=+0
(ii) x+%2B+3y+%2B+3+=+0
solve (i) for y as
(ii) y+=+2x+-+8
solve (ii) for y as
(iii) y+=+%28-1%2F3%29x+-+1
Now if you are to solve for x and y, we get
(3,-2)
