yes, i know that got three equations in four unknowns variables.
So in the question is want to solution with matrix, but i don't know how to start and end the result.
Can u help me?
Can anyone pls help to solve the solution set of the system of equations given above, where a, b, c are unknowns.
w+5x+6y-z=a
2w+2x+2z=b
-2w-x+y=c
