Question 452202
Solve by the elimination method. 
3x+4y=3 
6x+8y=6 

----------------------
Multiply thru the 1st equation by 2 to get:
6x + 8y = 6
6x + 8y = 6
-----------------
Subtract to get:
0 = 0
----
Although the original equation look different,
one is a multiple of the other.
---
The solution is all points of the form (x,(-3/4)x+(3/4))
where x is any Real Number.
