I Think of a number. If i subtract 8 from it and multiply the difference by 3 the result is 21. What is the number i am thinking of?

Answer 1

(n - 8) / 3 = 21

n - 8 = 63

n = 71

Answer 2

The answer is supposed to be 15

Answer 3

I'm sorry. I goofed. The problem states that the difference is multiplied, not divided, by 3.

3 (n - 8) = 21
3n - 24 = 21
3n = 45
n = 15

Answer 4

21

Answer 5

i hate this i dont understand

Answer 6

3(×-8)=21
3×-24=21
3×-24+24=21+24
3×÷45÷3
×=15

Answer 8

15
