45 legs
z = (x + 3) + 3 = x +
x + (x + 3) + (x + 6) = 39
3x + 9 = 39
3x = 30 / x = 10
13 × 1 = 13 legs
16 × 2 = 32 legs
Total = 0 + 13 + 32 = 45 legs
✅ 45 legs
=(16×2)+(13×1)+(10×0)
=32+13+0
=45
All the swans have 45 legs in total .
Total No of legs are:
=39+3×2+3-3
=39+6+0
=45
Hence the total number of legs are 45.
