Question
This is STRICTLY a helping question not a quiz....
Solve using Gauss-Jordan elimination.
2x+7x,- 23x3= 15
4X1 +3x,- 13x3= -3
X1+ X, - 4X3 = 0
Select the correct choice below and fill in the answer box(es) within your choice.
O A. The unique solution is x =
X2 =
and Xg
O B. The system has infinitely many solutions. The solution is x,
,X2=
and
%3D
1= Exp
(Simplify your answers. Type expressions using t as the variable.)
OC. The system has infinitely many solutions. The solution is x, =
X2 = S, and x, =t.
(Simplify your answers. Type an expression using s and t as the variables.)
O D. There is no solution.
