Question

Jacksons age was 2/5 of the age she will be in 20 years from now seven years ago. How old is jackson now?

Answer 1

Jackson's today’s age = x.

Jackson's age 7 years ago = x - 7.


Jackson's age 20 years from now= x + 20.


x - 7 = (2/5)(x + 20)


5 (x - 7) = 5 * (2/5)(x + 20) (multiply with 5 to both sides)


5x - 35 = 2x + 40



5x - 2x = 40 + 35


3x = 75


x = 25


Jackson  today's age =25 years .
