Question 319294
Notice right away that both y letters cancel each other out because one is positive and the other is negative.  

So, we are left with 2x = 3 + 4 or 7.

Solve 2x = 7 for x.

x = 7/2

The only solution to this system of linear equations is the point (7/2, 0).

In other words,, both lines (both equations) meet or cross each other at the point (7/2, 0).

Understand?
