[tex]9n=12+6[/tex]

[tex]9n=18[/tex]

[tex]\displaystyle \therefore n=\frac{19}{8}=\boxed{2}[/tex]

Therefore, the number is 2.

===============================

Problem: The difference between nine times a number and six is twelve. Find the number.

Solution: Let x be the number then solve it.

  • [tex]9x - 6 = 12[/tex]

  • [tex]9x = 12 + 6[/tex]

  • [tex]9x = 18[/tex]

  • [tex] \begin{gathered} \frac{ \cancel9x}{ \cancel9} = \frac{18}{9} \end{gathered}[/tex]

  • [tex]x = 2[/tex]

- Therefore, the number is:

  • [tex] \large \rm Number = \boxed{ \rm \green{ \: \: 2 \: \: }}[/tex]
