    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 ??

    is that the answer?

    using the same methodology as above.

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

    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

    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!
