7a+=+4+-+b
-
7a+=+3+-+b
______________________
7a-7a+=+4-3+-+b-%28-b%29
0=+1+-b%2Bb
0=+1%2B0..........no+solutions
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-7x%2B4%2C-7x%2B3%29+

From the graph, we can see that the two lines are parallel and will never intersect. So there are no+solutions and the system is inconsistent.
