the answer

Use Gaussian elimination to find the complete solution to the system of equations, or show that none exists. 7x+ y- z=7 9x + 9y - 8z = 9 .. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. There is one solution. The solution set is { ( )} (Simplify your answers.) O 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.) O C. There is no solution. The solution set is O
