Apples 5

In six crates are 45 kg of apples. Five crates were the same amount, and in the sixth crate were 3 kg more apples. How many kilograms of apples were in each crate?

Final Answer:

a =  7 kg
b =  10 kg

Step-by-step explanation:

$$\begin{gathered} 5a+(a+3)=45 \\ 5\cdot a+(a+3)=45 \\ 6a=42 \\ a=\frac{42}{6}=7 \\ a=7=7\text{kg} \end{gathered}$$

$b=a+3=7+3=10\text{kg}$
