Duck eggs = chicken eggs + 10

Duck eggs + Chicken eggs = 24
(10 + chicken eggs) + chicken eggs = 24

(10 + x) + x = 24 (where x is the number of chicken eggs)
x + x = 24 - 10
x + x = 14
x = 7 (ie 7 times 2 equals 14)

Duck eggs = 10 + 7 = 17
Chicken eggs = 7
Total eggs is 17 + 7 = 24

7 chicken eggs and 17 duck eggs = 24 eggs in total ??

using the same methodology as above.

jeez it made me think for a few minutes!! had to get out my pen and paper 😂😂😂

5. Or if you don't want to use equations:

First subtract the 10 extra duck eggs.
24 minus 10 = 14
This means you now have equal number of duck eggs and chicken eggs.

Then divide by 2
14 divide by 2 = 7

Therefore number of chicken eggs is 7 and number of duck eggs is 10 more than that = 17.

The math is same as what secret squirrel wrote. Just thought I would share my calculation as a different way of explaining if your ds is not familiar with algebra.

torn, not sure where I am heading right now.
I feel lost in limbo, trying to decide which path to take life down,
Thought I had it sorted but not so sure now,
this single parent thing isnt easy when youre wanting to just improve life

12. I worked out 17 and 7 by trial and error. Haha. Started with 14 and 4, then 15 and 5, then 16 and 6, then 17 and 7. Haha.

With those workings out @turquoisecoast I'm surprised this is what year 5s are expected to know!

13. Dad got 17 too but I was like HTH did you get that, that can't be right 😂 Sorry Dad! And thanks girls. I'll be back in Monday afternoon for more help hahaha.
