exactly, the most easy way to solve this is to add up the first 2 pictures together. which equals to picture 3 + 2 rabbits. aka 24 + 2 rabbits. meaning that 2 rabbits are 6 kg together. so picture 3 + 6 kg = 27 kg

this way you dont need to even bother calculating how much a dog or cat weighs. even though it wouldnt be that hard to calculate now.

actually the easiest way is too add all 3 together and you got
2*rabbit + 2* dog + 2*cat = 2*(rabbit+dog+cat) = 54kg
i.e. rabbit+dog+cat = 27kg

I messed some numbers up there, but the method is still there :/

just add everything and you have 2x?. then just divide by 2.

20+24+10=54. 54/2=27

that's actually a pretty interesting solution. It gets what you need and no more. I would have set up a system of equations

In the first 3 pictures, each animal appears twice. If you add their weight together and then take half of that total, you get how much all 3 weigh together, without actually calculating how much each of them weigh individually.

32kg.

The dog has put on weight since the neighbors started feeding it.

I did that in 9th grade c:

I r + c = 10
II r + d = 20
III c + d = 24

II - I d - c = 10
(II - I) + III 2d = 34

d = 1/2 x 34 = 17

r = 20 - 17 = 3

c = 10 - 3 = 7


r + c + d = 17 + 7 + 3 = 27

if it is then here is the solition:

x = rabbit
y = cat
z = dog

step 1: x + y - 10 = 0 = x + z - 20
step 2: solve above --> y - z + 10 = 0 = y + z - 24
step 3: 2z = 34
dog = 17 = z
step 4: Substitute z:
z + x = 20
17 + x = 20
Bunny = x = 3

Step 5 substitute x:
x + y = 10
3 + y = 10
cat = 7 = y

Dog = 17
Cat = 7
bunny = 3
Total = 27 kg

I feel like it is simpler just to say:
2(b+c+d)=54
2 because each animal is weighed twice in the picture, and 54 is the total of the three weighings

b+c+d = 54/2
=27

then you know that the bunny must be 3 kg because the weight of the dog/cat combo was 24... (27-24=weight of bunny), cat=10-3 ... so 7, and dog=20-3 so 17

Both ways get the same answer though, just this seems clearer in my head

If this was chemistry, you would be considered wrong because you have too many significant figures. Thank god no one likes chemistry anyway.
