Use Cramers Rule to solve the system
-x-3y=-8
2x+4y=12

and

Step-by-step explanation:

To use Cramer's Rule, we first need to turn this system of equations into a matrix

,

The first step to use Cramer's Rule is to find the determinant of the original matrix

Next, we need to replace column 1 of matrix A with b and then find the determinant of that matrix

And now we need to replace column 2 of matrix A with b and then find the determinant of that matrix

Now that all of this is done, we can find the values for our x matrix.

Recall that Cramer's Rule states that

Now that we know all of the required determinants, we can find x

This means that the solutions to this system are and
