Let x stand for rabbit.
y stand for cat and
z stand for dog.
x + y = 10.................(i)
x + z = 20.................(ii)
y + z = 24.................(iii)
From eqn (i)
x = 10 - y...................(iv)
Substitute eqn (iv) into eqn (ii) above
10 - y + z = 20
y - z = -10 ..................(v)
Solving eqns (iii) and (v) simultaneously
y = 7..................(vi)
z = 17..................(vii)
Substitute eqn (vi) into eqn (iv)
x = 10 - y
x = 10 - 7
x = 3....................(viii)
Taking eqn (vi) + eqn (vii) + eqn (viii)
7 + 17 + 3 = 27
Therefore the total mass of animals is 27 kg
