Question 909333
hi can you pls help me with this problem? In 4 years time, Maria's mother will be three times as old as Maria. Six years ago, her mother was seven times as old as her. Find their present ages.
***
6 ys ago:
x=marie's age
7x=mother's age
..
At present:
x+6=marie's age
7x+6=mother's age
..
In 4 yrs time:
x+10=marie's age
7x+10=mother's age
7x+10=3(x+10)
7x+10=3x+30
4x=20
x=5
..
x+6=5+6=11 (marie's present age)
7x+6=41= (mother's present age)
