calculate the coordinates of the intersection of the two lines
1. y + 2x = 3
2. y - x = 2
y + 2x = 3 --------- eq (i)

y -  x = 2 --------- eq (ii)

3x = 1 ------------- Subtracting eq (ii) from eq (i)

x+=+1%2F3



y+-+1%2F3+=+2 ----------- Substituting 1%2F3 for x in eq (ii)

y+=+2+%2B+1%2F3

y+=+2%261%2F3
