Question
Use Gaussian elimination to find the complete solution to the following system of equations, or show that none exists.
9x1 + 29x2 + X3 = 15
4x, + 13x2 + 2x3 = -7
X, + 3x2 - 3x3 = 5
Select the correct choice below and, if necessary, fillin the answer box(es) to complete your choice.
A. The unique solution is X, =, X2 =
and X3 =
B. The system has infinitely many solutions. The solution is x, =
,X2 =
and x, =t.
(Simplify your answer. Type an expression using t as the variable.)
C. The system has infinitely many solutions. The solution is x, =
, X2 =s, and x, =t.
(Simplify your answer. Type an expression using s and t as the variables.)
D. There is no solution.
