Jackson is thinking of a number, which if you triple it and subtract 13, ends with a result of 2. What number is Jackson thinking of?

Question

 hint: use a variable

Answer 1

3x-13=2

 

3x = 2+13

 

3x =15

 

x= 5

 

[X= the number that Jackson is thinking of]

 

[3x = triple the number Jackson is thinking of]

 

Check:  If Jackson is thinking of the number 5.  Triple the number 5 is 15.  Subtract 13 from 15 and you get 2.
