Hi there, i'm just working my way through numeraid and i'm answering some of the questions on there and i've come across your question.
00:06
I thought we would attack this question with a solution.
00:10
So let's write it out in a bit better.
00:12
So minus 14x minus 6 is equal to x minus 15.
00:19
Now our goal here should be to get x on its own on one side and a number on the other.
00:24
So let's try and move some numbers around and see what we can do.
00:28
So i think it might be easy to move the 6 to the right.
00:33
So put the line down the middle, plus 6 onto both sides and now the 6 has disappeared from the left.
00:40
I end up with just minus 14x is equal to and on the right now i've got x and whatever minus 15 plus 6 is, which is just minus 9.
00:50
Now i need to move this x to the left so i'm going to take away x on both sides and i end up now with quite a nice solution of minus 15x.

Let's put this bit here...
