Use GaussJordan row reduction to solve the given system of e
Use Gauss-Jordan row reduction to solve the given system of equations. (If there is no solution, enter NO SOLUTION. If the system is dependent, express your answer in terms of x, where y = y(x) and z = z(x).) x + y + 6z = 3 1/3x + 1/3y + 2/3z = 1 1/2x + z = 0 (x, y, z) = () Use Gauss-Jordan row reduction to solve the given system of equations. (If there is no solution, enter NO SOLUTION. If the system is dependent, express your answer in terms of x, where y = y(x) and z = z(x).) -1/2x + y - 1/2z = 0 -1/2x - 1/2y + z = 0 x - 1/2y - 1/2z = 0 (x, y, z) = ()
Solution
1)
Your matrix
Find the pivot in the 1st column in the 1st row
Eliminate the 1st column
Make the pivot in the 2nd column by dividing the 2nd row by -2/3
Eliminate the 2nd column
Find the pivot in the 3rd column in the 3rd row (inversing the sign in the whole row)
Eliminate the 3rd column
Solution set
x = -3
y = -3
