Question

I am thinking of a number. I add 13 to this number and then

multiply by 2. The answer is 36. What is the number I was thinking
of? (you may like to write an equation to represent this problem,
but any

Answer 1

Number = 5

Explanation:

• We can let n represent the unknown number.

• Since 13 is added to the number, and the product of this and 2 equals 36, we can use the following equation to find n, the value of the unknown number:

((n + 13) * 2 = 36) / 2

(n + 13 = 18) - 13

n = 5

Thus, the number is 5.

13 added to 5 is 18 and 18 multiplied by 2 is 36, which means 5 as an answer is correct.
