Web1. The system of equations can be written in matrix form as follows: To solve for x and y, we can use the inverse matrix method. First, we need to find the inverse of the coefficient matrix: Next, we can multiply both sides of the equation by the inverse matrix: Therefore, the solution to the system of equations is x = -1/2 and y = 3/2.
