5x + 2y = 7
multiplying this equation by 2
10x + 4y = 14 ...(A)

-2x + 6y = 9
multiplying this equation by 5
-10x + 30y = 45 ... (B)

Add (A) and (B),
10x-10x + 4y +30y = 14+45

0 + 34y = 59

y = 59/34
y = 1.7

The age of Oscar is 1/3of his sister .after 12 years his age will be half that of his sister. What is Oscar's current age
Radda [10]

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
