1) 5x+7y= 3. 2x+3y= 1. The denominator block [which I would call determinant or matrix if the text editor would provide decent graphics] is 5 7 2 3. Its value is 1. [5*3  2*7 = 15  14.] The par column is 3 1, so the x numerator block is 3 7 1 3. Its value is 2. [9  (7).] With a denominator of 1, this also means x = 2. The y numerator block is 5 3 2 1. Its value and the value of y = 1.
