Answer:
Step-by-step explanation:
Answer:
Let's denote:
Age of Oscar : x
Age of Oscar's sister : y
Then, we have:
3x = y(1)
2(x + 12) = y + 12(2)
Substitute y from (1) into (2), then:
=> 2(x + 12) = 3x + 12
=> 2x + 24 = 3x + 12
=> x = 24 - 12
=> x = 12
=> Oscar's current age: 12
8 = 3x would be your answer
Have a good day :)
