Question

Six times a number is greater than 20 more than that number. What are the possible values of that number?

N<4
N>4
N> 20/7
N<20/7

Answer 1

N>4

Explanation:

Plugin numbers based on your options. Just check if any number less than four fits, if not, next option. In this case if you plug in 4, 4 * 6 = 24 which is equal to 20 more than 4 which is 24. Since our option is N>4 we can try 5 which will work and so will every number after that.
