I think of a number add 8 and multiply the result by 6 the answer is 66 what is the number i first thought of?
Question asked by: knowitall
Whenever you get a question like this, the first is to turn it into a mathematical expression you can work with, standardly the unknown number is written as 'x'.
So here we turn the words into:
6(x+8) = 66
Multiplying out the brackets, we then get:
6x + 48 = 66
Which we then re-arrange by doing 66 - 48 to get:
6x = 18
Then we divide through by 6 to get:
x = 3
And so there is the answer: the number is '3'.
