Question

Write the system of equations as a matrix equation AX=B, with A as the coefficient matrix of the system.x+2y=−112x+6y=−30

Answer 1

The matrix equation is given to be:

`AX=B`

where A is the coefficient matrix of the system.

To get the value of X, we need to multiply both sides of the equation by the inverse of A, since:

`A\cdot A^(-1)=1`

Therefore, we have:

`X=A^(-1)\cdot B`

he TLAST OPTION is correct.
