You can put this solution on YOUR website! If Lauren's age is 11 years more than four times Robert's age, their age difference cannot be 2. Assuming age difference 20, the solution will be as below:
Let Robert's age be r
Therefore Lauren's age = 4*r + 11
By condition, 4r + 11 - r = 20
or, 4r - r = 20 - 11
or, 3r = 9
or, r = 9/3 = 3
Therefore Lauren's age = 4*3+11 = 12 + 11 = 23 years
