Question

Five years ago a was three times old as b and then 10 years later i shall be twice as old as b what are the purpose a present ages of a and b in years

Answer 1

Answer:

Step-by-step explanation:

let’s call A age as X, B age as Y then

X-5 = 3 ( y-5)

X-5= 3y- 15

X-3y= -15+5

x-3y= -10

Ten years later,

X+10 = 2 (y+10)

X-2y= 10

then from x-3y= -10, X-2y= 10 then y= 20, then x-60= -10 then x=50.
