A truck is loaded with two different types of crates. When 20 of crate A and 25 of
crate B are loaded, the truck’s 8 tonne capacity is reached. When 2 of crate A and 16
of crate B are loaded, the same capacity is reached. Calculate the mass of each crate. Simultaneous equation please
20A + 25B = 8
2A + 16B = 8 ---> A + 8B = 4 ----> A = 4-8B
Use substitution ....
