Simultaneous equations can be solved using inverse matrix operation.
The complete steps of Jacob's solution are:
We have:
Calculate the determinant of
So, the inverse matrix becomes
Replace the first column with to calculate the value of x
So, we have:
Replace the second column with to calculate the value of y
So, we have:
Hence, the complete process is:
