Question: the answer Use Gaussian elimination to find the complete solution to the system of equations, or show that none exists. x + 3y - 2z

the answer

Use Gaussian elimination to find the complete solution to the system of equations, or show that none exists. x + 3y - 2z - W= 12 4x + y + 2z + 5w=20 - 3x - y+z-2w= - 14 x -y - 3z - 4w= - 14 . . . Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. There is one solution. The solution set is . (Simplify your answers.) B. There are infinitely many solutions. The solution set is { ( , , ,w) }, where w is any real number. (Simplify your answers. Type expressions using w as the variable. Use integers or fractions for any numbers in the expression.) O C. There is no solution. The solution set is O. More
