Solve the following system of equations using the inverse of the coefficient matrix,
2x + 4y = -9
-x - y = 2
My attempt-
[2 4 [x = -9
-1 -1] y] = 2
|A| x b
|A| = -2-4=-6
[x = 1/-6 [-1 -4 [-9 1/-6 [ 1 = 0.03
y] = 1 2] 2] -5] = 0.166666
Would someone be able to confirm if the answer is correct please???
Thank you
