The point of intersection of the graphs of the lines
2x - y = 3 and x + y = 3 is the solution of the simultaneous equations derived from the two lines.
So
2x - y = 3 ------------------------------------------------(1)
x + y = 3 -------------------------------------------------(2)
Now adding equation (1) to equation (2), we have:
3x = 6
Then
x = 6 / 3 = 2
Substituting x = 2 into equation (2), we have
(2) + y = 3
Hence
y = 3 - 2 = 1.
Therefore, the point of intersection is (2, 1).
