Susi is 25 years younger then her mother.
In 7 years the mother will be 5 times older then Susi.
:
There is a reason why you can't figure this out, it is impossible
We will do the problem and see that
;
s = Susi's present age,
m = Mother's age
:
Write an equation for each statement:
:
"Susi is 25 years younger then her mother."
s = m - 25
or we can say
m = s + 25
:
In 7 years the mother will be 5 times older then Susi.
m + 7 = 5(s + 7)
Simplify
m + 7 = 5s + 35
m = 5s + 35 - 7
m = 5s + 28
now, replace m with (s+25), from the 1st statement
s + 25 = 5s + 28
25 - 28 = 5s - s
-3 = 4s
s = , a nonsensical solution, perhaps they meant 7 year ago!!
or they meant
"In 7 years the mother will be 5 times older then Susi is now!"
