[tex]2(n-7) = 2[/tex]

Step-by-step explanation:

The statement says 2 multiplied by (n-7) is 2.

We say [tex]2(n-7) = 2[/tex].

If you want to know the actual answer, it is [tex]2n-14 = 2[/tex] which is finally [tex]2n-16 = 0[/tex].

From here, we can say [tex]2n=16[/tex] and simplified, this gives n = 8.
