Answer:

[tex]21[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be that number.

[tex]12x-216=2x-6[/tex]

[tex]12x-2x=-6+216[/tex]

[tex]10x=210[/tex]

[tex]10x/10=210/10[/tex]

[tex]x=21[/tex]

21 is the number.

Let n, equal that number.

12n - 216 = 2n - 6

Solve for n:

12n - 216 = 2n - 6

12n - 216 + 216 = 2n - 6 + 216

12n = 2n + 210

12n - 2n = 2n - 2n + 210

10n = 210

10n/10 = 210/10

n = 21

Therefore, the answer si 21.

Best of Luck!
