Matrix A= 2x2, R1= -1, -1, R2= -7, 3
Matrix b= 2x2, R1= 1,0, R2= 0, 1
A*?=b
____________
To solve, I put ? on the one side of the equation as ?=A^(-1)b. My answer is then just the inverse of A, because what is multiplied by the identity matrix is itself. It is shown to be incorrect.
?=2x2, R1= -3, -1, R2= -7, -1
Please help! I would like this to become more intuitive.
Also, is there a way to format matrices on the forum?
