Question

Use Gaussian elimination...

Use Gaussian elimination to find the complete solution to the following system of equations, or show that none exists. - X+ y + z = -1 - X + 3y - 72 = -9 4x - 3y - 8z = 0 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. There is one solution. The solution set is {0 1 }. (Simplify your answers.) OB. There are infinitely many solutions. The solution set is {(, 2) }, where z is any real number. (Type expressions using z as the variable. Use integers or fractions for any numbers in the expressions.) O C. There is no solution. The solution set is Ø.
