Question 1190170
<br>
A different setup, using only one variable -- using the information that the mother was 5 times as old as Agnes 6 years ago....<br>
Let x = age of Agnes 6 years ago
Then 5x = age of mother 6 years ago<br>
Their current ages are
x+6 = Agnes
5x+6 = mother<br>
The mother is now 3 times as old as Agnes:<br>
5x+6 = 3(x+6)
5x+6=3x+18
2x=12
x=6<br>
ANSWER: Agnes' age now is x+6=12<br>
CHECK: 5x+6=20+6=36 = 3(12)<br>
