Answer:
x₁ = 0, x₂ = -t, x₃ = t
Step-by-step explanation:
consider
m = no. of non zero rows in reduced echelon form = 2
n = no. of unknowns = 3
Using the fact that
m < n ⇒ solution is non-trivial
As last row is zero so we can say x₃ is a free variable i.e
x₃ = t
From second row:
[tex]x_{2]+x_{3}=0\\x_{2]=-x_{3}\\x_{2]=-t[/tex]
From first row
x₁ = 0
