Question

Can u guys PLEASE answer question g. THIS IS URGENT

Answer 1

8 years

Explanation:

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

Answer 2

Laura is 8

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
