2( n+12) = 1.5( 2n +12)
2 n + 24 = 3 n + 18

Actually that is not my name
x = the number
When you add 12 to the number,it will be:
x + 12
When you double it,
it will be:
2 ( x + 12 ) = 2 x + 24
the result = 1.5 ( 2 x + 12 ) =
3 x + 18
therfore:
2 x + 24 = 3 x + 18
Subtract 2x to both sides.
24 = x + 18
Subtract 18 to both sides.
6 = x
x = 6
