Question: In Problems 1956, solve each system of equations. If the system has no solution, state that it is inconsistent. For Problems 1930, graph the lines

In Problems 19–56, solve each system of equations. If the system has no solution, state that it is inconsistent. For Problems 19–30, graph the lines of the system. x = y + z = -4 - 2x - 3y +

x = y + z = -4 - 2x - 3y + 4z = -15 5x + y2z = 12
