    a) Let Sheik and Ingrid's age be x and y, When Ingrid was born Sheik was 24 so we get \[x-y=24\] In three years the sum of their ages is 68, so \[(x+3)+(y+3)=68\] I think you can do now, @GOODMAN

    Let Gunta=x and Dad=y Gunta's dad is 25 years older than Gunta, so, y=x+25 The sum of their ages is 61 x+y=61 I dont know if i did it right...

    In both the cases, x and y will give us the present ages
