Unformatted text preview: xcoefficient below row 1. Eliminate the ycoefficient below row 5. Reinserting the variables, this system is now Equation (9) now can be solved for z . That result is substituted into equation (8), which is then solved for y . The values for z and y then are substituted into equation (7), which then is solved for x . The check is left to you. The solution is x = 2, y = 1, z = 3....
