y+=+2x+-+1....eq.1
y+=+x+%2B+1....eq.2
________________________
since left sides both equal, then right sides must be equal too
+2x+-1=x+%2B+1..........solve for x
+2x+-x=1+%2B+1
+highlight%28x=2%29
go to
y+=+x+%2B+1....eq.2 plug in 2 for x
y+=+2+%2B+1
highlight%28y+=+3%29
so, lines intersect at point (2,3)
