Let us assume the number of hours volunteered by Katie = x
Number of hours volunteered by Elizabeth = y
Number of hours volunteered by Siobhan = z
After one week,
x = y + 3
z = y - 1
After 3 weeks
3x = 3 (y + z)
Dividing both sides by 3, we get
x = y + z
Putting the value of x from the first equation in the third equation, we get
x = y + z
y + 3 = y + z
z = 3
Now putting the value of z in the second equation, we get
z = y - 1
3 = y - 1
y = 4
Putting the value of y in the first equation, we get
x = y + 3
= 4 + 3
= 7
The number of hours volunteered by Katie = 7 hours
Number of hours volunteered by Elizabeth = 4 hours
Number of hours volunteered by Siobhan = 3 hours

The flower that smiles to-day
To-morrow dies;
All that we wish to stay
Tempts and then flies.
What is this world's delight?
Lightning that mocks the night,
Brief even as bright.
