Question

Anil says, “I am thinking of a number. When I divide it by 3 and then add 5, my answer is twice the number I thought of”. Find the number.

Answer 1

Answer:

let x be the number you’re thinking of.

When you divide the number by 3 you have x/3

When you add 5 to that number you have x/3 +5

And this (x/3+ 5) is equal to twice the original number (2x)

So…

x/3 +5 = 2x

you need to solve for x. Multiply both side of the equation by 3 to give you

x + 15 = 6x

subtract x from both sides of the equation to give you:

15 = 5x

divide by 5 to get x = 3

Your original number is 3.
