Question 1081757: Please help me solve this equation: a girl is 15 years younger than her aunt, in 10 years time the girl's age will be 1/2 of her aunt's age. find the girls present age. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! girl is x years old
aunt is x+15.
x+10=(1/2)(x+25), this is adding 10 to each age
2x+20=x+25
x=5 girl
aunt is x+15= 20
in 10 years, girl will be 15, aunt 30.
