Use matrix inversion to solve for Y and i, given IS: 0.4Y150i = 209 LM: 0.1Y250i = 35 Setting up the augmented matrix, 0.4 150 1 0 0.1 -250 0 1 1a. Multiplying row 1 by 2.5 to obtain 1 in the a11 position, 1 375 2.5 0 0.1 -250 0 1 1b. Subtracting 0.1 times row 1 from row 2 to clear column 1, 1 375 2.5 0 0 -287.5-0.25 1
