Let Yancy's age be = x years

Let her sister's age be = y years

Given is , Yancy is 2 years older than 3 times her younger sister's age, so equation is formed like

x=2+3y  .... (1)

Also given, as her younger sister is 6 years old.

So, y=6

Putting y= 6 in equation (1)

x=2+3(6)

x=2+18

x=20

Hence, Yancy is 20 years old.
