Perform one step of row reduction, in order to calculate the values for x and y

Question

Perform one step of row reduction, in order to calculate the values for x and y by back substitution. Then calculate the values for x and for y. Also calculate the determinant of the original matrix. You can let webwork do much of the calculation for you if you want (e.g. enter 45-(56/76)(-3) instead of calculating the value out). You can also use the preview feature in order to make sure that you have used the correct syntax in entering the answer. [Note-- since the determinant is unchanged by row reduction it will be easier to calculate the determinant of the row reduced matrix.]

Explanation / Answer

y = 8/75 x = -21/125 det = -1225
