WebAnswer (1 of 6): If xy=8 then y=8/x If we wish to minimize 2x+y=2x+8/x=z We need dz/dx=0 and dz/dx swaps from - to + z=2x+8/x dz/dx=2–8/x^2 dz/dx is zero at x=\pm 2 We know … WebExpert Answer. Transcribed image text: Consider the system of equation: 2x+3y −z = 8 x− 4y +2z = −1 and 5x+2y 2x +3y−z = 15 = 8 The second system is obtained from the first by adding twice the first equation to the second equation, and then swapping the two equations. What is true about the solutions of the two systems?
