## GOODMAN 3 years ago Having trouble setting these problems up :/ a) Mrs.Sheik was 24 years old when Ingrid was born. In three years, the sum of their ages will be 68. how old is each now? b) Gunta's dad is 25 years older than Gunta. The sum of their ages will be 61. How old is Gunta?

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

Ohhhh..okayy!!! Thanks! The same applies to the other problem as well?

3. ash2326

Yeah, Could you write the equation for second one?

4. 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...

5. ash2326

Correct:D Good work @GOODMAN

6. GOODMAN

So exactly how would i find the ages..im still a little confused about all the variables.

7. ash2326

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

8. GOODMAN

Okay!

9. ash2326

Did you understand?

10. GOODMAN
