Using Cramer's Rule to Solve a System of Two Equations in Two Variables

1. We eliminate one variable using row operations and solve for the other.
2. Now, solve for x.
3. Similarly, to solve for y,we will eliminate x.
4. Solving for y gives.
5. Notice that the denominator for both x and y is the determinant of the coefficient matrix.
