Mathematically, it does not matter. But it can be harder and you do need to know exactly what you are doing.

For example, if you need to solve 5x + 3 = 23

the conventional 2-step method is as follows:

Step 1: 5x + 3 - 3 = 23 - 3

which gives 5x = 20

Step 2: 5x/5 = 20/5

so that x = 4.


But you could also have done

Step 1: 5x/5 + 3/5 = 23/5

which gives x + 3/5 = 23/5

Step 2: x + 3/5 - 3/5 = 23/5 - 3/5

ans so x = 20/5 = 4 as before.
