Answer: 3,4,7
Step-by-step explanation:
Is this an a level question...
Stacy's present age = x
Laura's present age = 8 + x
Laura's age next year = (8 + x) + 1
Also, Laura's age next year = 3x
Therefore,
3x = (8 + x) + 1
3x = 9 + x
3x - x = 9
2x = 9
x = 9/2
x = 4.5
Laura's present age = 8 + x = 8 + 4.5 = 12.5
