A number divided by 2 is equal to 12 less than the original number what is the number?
n ÷ 2 = n - 12
n ÷ 2 × 2 = (n - 12) × 2
n = 2n - 24
n = 24
Hence, the number = 24
n ÷ 2 = n - 12
n ÷ 2 × 2 = (n - 12) × 2
n = 2n - 24
n = 24
Hence, the number = 24

the number we assume to be n , then n/2 = n-12
so n = 2n -24 , therefore , n = 24 , thus 24 divided by 2 becomes equal to half of 24 which is 12...

x/2 = x - 12
12 = x/2
x = 24
12 = x/2
x = 24

24.

Let x be the original number.
Then
x/2 = x - 12
x = 2x - 24
x = 24
Then
x/2 = x - 12
x = 2x - 24
x = 24

24?

24, because 24/2 is 12, which is 12 less than the original number which is 24.

n / 2 = n -12
solve for n
n = 2n - 24
n = 24
solve for n
n = 2n - 24
n = 24
