Answer:

The symbol can be [tex]\neq, >[/tex]

Step-by-step explanation:

Given : Expression   [tex]12\div x+2x\ ?\ 12\div (x+2x)[/tex]

To find : Which symbol creates a true sentence when x = 6?

Solution :

[tex]12\div x+2x\ ?\ 12\div (x+2x)[/tex]

We put x=6 both side and get the result,

LHS, [tex]L=12\div x+2x[/tex]

[tex]L=12\div 6+2(6)[/tex]

[tex]L=2+12[/tex]

[tex]L=14[/tex]

RHS, [tex]R=12\div (x+2x)[/tex]

[tex]R=12\div (6+2(6))[/tex]

[tex]R=12\div (6+12)[/tex]

[tex]R=12\div 18[/tex]

[tex]R=0.6[/tex]

So we can say that,

[tex]14\neq 0.6[/tex] or [tex]14> 0.6[/tex]

[tex]12\div x+2x\ \neq\ 12\div (x+2x)[/tex]

or [tex]12\div x+2x\ >\ 12\div (x+2x)[/tex]

Therefore, the symbol can be [tex]\neq, >[/tex]
