Crates 2

In six crates is 45 kg of apples
Five crates are equally apples.
In the first crate is 3 kg more apples.

How many kilograms are in each crate?

Correct answer:

a =  10 kg
b =  7 kg
c =  7 kg
d =  7 kg
e =  7 kg
f =  7 kg

Step-by-step explanation:

$$\begin{gathered} a+5(a-3)=45 \\ a+5\cdot (a-3)=45 \\ 6a=60 \\ a=\frac{60}{6}=10 \\ a=10=10\text{kg} \end{gathered}$$

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

$c=a-3=10-3=7\text{kg}$

$d=a-3=10-3=7\text{kg}$

$e=a-3=10-3=7\text{kg}$

$f=a-3=10-3=7\text{kg}$
