Answer 2

Answer:

y = 30

Step-by-step explanation:

Let Sana's age be 'y'

Let Mona's age be 'x'

The equation of Sana is senior to Mona

= x + 18 = y

After 6 years, the equation = 2x + 6 = y + 6

x + 18 + 6 = 2x + 12

x + 24 = 2x + 12

3x = 24 + 12

3x = 36

$\sf x = \frac{36}{3} = 12$

y = x + 18

y = 12 + 18

y = 30
