- let x be the mother's age and y be the son's age
x-5=5(y-5)
x+5=3(y+5)-8
by solving this we get x=35 and y=11 - 12 years agoHelpfull: Yes(1) No(1)
- x-5=5(y-5)
x+5=3(y+5)-8
5y-15=3y+15-8
2y=22
y=11
and x=35 - 12 years agoHelpfull: Yes(0) No(0)
- suppose age of son=y and age of kate=x
x-5 = 5(y-5)----------(1)
(x+5)+8 = 3(y+5)--------(2)
by equation (1) and (2) we can say that
age of son(y)=11 and age of kate(x)=35
