Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old
8 years
Daniel's current age: D
Laura's current age: L
D = 2L (1)
D - 4 = 3(L - 4) (2)
(2) D - 4 = 3L - 12
D = 3L - 8
(1) 3L - 8 = 2L
L = 8
