Question

4) Rohit said, "I have thought of a number. If you
add 7 to 3 times the number, you get 31. What
number have I thought of?" Can you answer
Rohit's question?​

Answer 1

Answer:

Assume that the unknown number is x

7 + 3x = 31

3x = 31 - 7

3x = 24

x = 24 ÷ 3

x = 8

Hence the number that Rohit thought of was 8
