Show equation AX=B represents a linear system of two equations in two unknowns. Solve the system and substitute into the matrix equation to check results. I have no idea can you help me out
The matrix equation AX=B results in the system of equations
x1 + 2x2 = -4
-3x1 + 5x2 = 12
I am sure you can solve that.
