Hi, re TY, note highlighted.
Please carefully follow the work, so as you may learn how to others like it.
Solve the system of equations by using the inverse of the coefficient matrix.
x+6y=-16
-5x+6y=8
A+=+%28matrix%282%2C2%2Ca1%2Cb1%2Ca2%2Cb2%29%29+=+a1b2-b1a2
A+=%28+matrix%282%2C2%2C1%2C6%2C-5%2C6%29%29 = highlight%2836%29
A%5E%28-1%29+=+%281%2F%28a1b2+-+b1a2%29%29%28matrix%282%2C2%2Cb2%2C-b1%2C-a2%2Ca1%29%29
