Now we combine like terms, nothing we can do on this side let’s combine things over here. 5x plus 10 stays the same this less 10, 5x minus 4. Trying to solve for x we need to subtract 5x from either of the sides. However the times both sides so actually when you subtract it it disappears altogether.

We subtract 5x subtract 5x leaving us with 10 is less than -4. Let’s think about this for a second is 10 actually less than -4? Not really so what’s happening here is we actually have a false statement this isn’t true which means that no value of x will actually work.

Okay I’m going to go back to this statement right here 5x is just a number. Here we have a number plus 10 here we have a number minus 4, there’s no way that when we minus it we are going to get bigger number than we add 10. So what this tells us we work it through and we end up with false statement this tells us this problem has no solution. No values of x will make these true.
