Let  x   be the age of Lara now
thus the age of Jose is    2x
five years ago age of Lara =  x-5
                       age of Jose =  2x-5
so the equation is
   2x-5 =  3(x-5)          /  3 times as old as Lara
   2x -5 = 3x -15
   x = 10
Lara present age =  10 years
Jose present age = 2x  = 2 . 10
                             =  20 years
