1. What is Gaussian Elimination with backward substitutions?

Explain your answer by solving this problem using the following equations:

x + y = 3

3x -4y = 2

2.  After explaining the Gaussian elimination, use MATLAB to solve the same  problem above by creating matrix A and B from the equations:

x = inv(A) * B  

or 

x = A\B
