Answer 1

Hello Yuvraj,

I will help you answer the first question and based on hopefully understanding it, you'll be able to answer the other ones on your own.

Let's pretend the mystery number of the first question is x. If the question is saying 5 times the sum of x and 2 is 35, the equation will look like:

5*(x+2)= 35 5 times the sum of x plus 2, is 35

From here you just solve it

5x + 10 = 35

5x = 35-10 = 25

x = 25 / 5 = 5

So the mystery number is 5.

Do you feel able to solve the rest of the questions on your own?
