You can use them to find a variable.
Lets say you have two equivalent expressions with the same variable...
x + 2x - 42 = 0
2x - 28 = 0
If you combine these equivalent expressions you ahve...
x + 2x - 42 = 2x - 28
In all of the expressions you have x = 7
There are also other applications but its confusing to explain.
