Question 195765: Hi, found another Matri problem Im struggling with.
This time I have to write the following system of equations:
x + 2y = 6
3x + 4y = 2
In matrix form and solve using inverse matrix.
Solve using eliminator procedure also and compare the two answers.
Again detailed solutions with explanations would be super helpful.
Thanks again- Nick.
