Calculate the weight of one small parcel, in grams
I will mark as brainliest for the right answer

Answer:
It's an equation, since they are balanced on the scale
x(large parcel)+1.325 kg + 3y(small parcel) = x+2.4kg
subtract x from both sides
3y + 1.325 kg = 2.4 kg
3y = 2.4 kg - 1.325 kg
3y = 1.075 kg
y= 1.075/3 = 0.35833333333333333333333333333333 kg
1kg = 1000g
one small parcel = 358.33333333333331439 g
