Let Luckee's age=x
Lovely's age=y
x-5=3(y-5)
x-5=3y-15
x-3y=-10
x+10=2(y+10)
x+10=2y+20
x-2y=10
x=2y+10
2y+10-3y=-10
-y=-20
y=20
x=40+10
=50
Luckee is 50 years old
Lovely is 20 years old.
Lovely's age=y
x-5=3(y-5)
x-5=3y-15
x-3y=-10
x+10=2(y+10)
x+10=2y+20
x-2y=10
x=2y+10
2y+10-3y=-10
-y=-20
y=20
x=40+10
=50
