The accompanying figure shows known flow rates of hydrocarbons into and out of a network of pipes at an oil refinery. E 200 X3 D 150 X5 X4V 200 25 A X2 B 175 C (a) Set up a linear system whose solution provides the unknown flow rates. XI 25 X2 175 X3 Find A so that A = y where = 200 and y= 150 X5 200 X6 Form the system so that the first equation represents node A, the second equation node B, etc. Then take all the variable to one side such that all the constants are on one side and positive. From the equations form the required matrices and enter the appropriate values for A below. A = X₁ x6 Mi
