Use Gaussian elimination to find the complete solution to the system of equations, or show that none exists
{ x+y- 5z=5
8x-y-16z= -3
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. There is one solution. The solution set is {( , , )}.
(Simplify your answers. Use integers or fractions for any numbers in the expressions.)
B. There are infinitely many solutions. The solution set is {( , ,z)}, where z is any real number.
(Simplify your answers. Type expressions using z as the variable. Use integers or fractions for any numbers in the expressions.)
C. There is no solution. The solution set is ∅.
