Sagot :
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
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
