A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?

                                                    Explanation:
                                                Let the mother's present age be x years.
| Then, the person's present age = | ![]()  | 
    2 | x | ![]()  | 
    years. | 
| 5 | 
![]()  | 
    ![]()  | 
    2 | x + 8 | ![]()  | 
    = | 1 | (x + 8) | 
| 5 | 2 | 
 2(2x + 40) = 5(x + 8)
 x = 40.

                Can anybody explain me?
(2x+40)/5 = (x+8)/2.
4x + 80 = 5x + 40.
                (2x+40)/5 = (x+8)/2.
4x + 80 = 5x + 40.
