Answer:

[tex]x=2[/tex].

Step-by-step explanation:

The given rational expression is [tex]\frac{6x-12}{x-7}[/tex].

To find the x-value that makes the rational expression zero, we equate the whole function or just the numerator to zero and solve for x.

This implies that:

[tex]\frac{6x-12}{x-7}=0[/tex]

[tex]6x-12=0(x-7)[/tex].

[tex]6x-12=0[/tex].

[tex]6x=12[/tex].

Divide both sides by 6

[tex]x=2[/tex].

Therefore x=2 makes the rational expression zero.
