4. Which cannot describe a system of linear equations?
A) no solution
B) exactly two solution
C) infinite solutions
D) exactly one solution




Sagot :

The is asking to choose among the following choices that cannot describe a system of linear equations and base on the choices, I would say that the correct answer among them is in letter B. exactly two solution, I hope you are satisfied with my answer and feel free to ask for more 

A system of linear equation can have no solutions , many solutions or exactly one solution .

Let's check out example of each.

[tex]No \ Solution \\ x+y =2 \\ x+y=4[/tex]

[tex]Many \ solutions x+y =2 \\ 2x+2y=4[/tex][tex]Exactly \  one \  solution \\ x+y =2 \\ x-y=4[/tex]

So all of these describes a system of  linear equations except two solutions.

So the correct option is B
