let present age of b=x
................ ................a =5x
5 year ago
age of a= 5x -5
age of b= x-5
A/q
(5x-5)=2(x-5)
5x-2x= -10+5
3x= -5
ques has some mistake , plzzz check

Hey.....!!! here is ur answer....☺️☺️
__________________________
__________________________
Let, the age of 'a' = X years
and the age of 'b' = Y years
__________________________
Then, according to the question...
(X–5) = 2(Y–5)----------(1)
& X = 5Y---------(2)
From equation (2) the X = 5Y
put up this value of X in equation (1)
(5Y–5) = 2Y–10
5Y–5 = 2Y–10
5Y–2Y = –10+5
3Y = –5
Y = –5/3
and from equation (2)
X = 5Y
X = 5×(–5/3)
X = –25/3
then the sum of their ages = X+Y =
–5/3+(–25/3)
–30/3
–10years
I hope this may help you.......✌️✌️✌️
THANK YOU......☺️☺️☺️
