You can put this solution on YOUR website! Find the point of intersection of the pair of straight lines.
y = x - 3
8x - 3y - 54 = 0
------
Substitute for "y" and solve for "x":
8x -3(x-3)-54 = 0
8x -3x + 9 -54 = 0
5x - 45 = 0
5(x-9) = 0
---
x = 9
==================
Substitute for "x" and solve for "y":
y = 9-3 = 6
----
Intersection: (9,6)
========================
