Question

I add 12 to a number and then double their result the result is one and a half times what I get when I double the original number and add 12 find the number

Answer 1

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

Answer 2

Actually that is not my name

Answer 3

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
