Janine and her older sister Ingrid's ages are consecutive even numbers. When Janine's age is divided by seven, and Ingrid's age is divided by three, the sum of those numbers is fourteen. Howold are Janine and Ingrid?

janine = x      Ingrid = x+ 2  

 

x/7   + ( x+2)/3   = 14      multiply through y 21

3x    + 7 (x+2) =  294

10x = 280

x = janine = 28 y/o     ingrid = 30 y/o
