Walt: Model and solve linear equations

You can solve 5a + 8 = 18 

First you - 8 from the 8 then you do the same to the 18 then you have 5a = 10 

Then you look at the 5a you have to do 

5 divided by 10 that is 2 so then you have your answer     a = 2

So if you had 5 + z = 10   z = 5

My next step is to solve larger harder equations
