Well atleast I got it right, BUT they will probably take points of due to my incorrect method, it's just I've been taught so many methods I'm just SO confused

It's difficult to explain in writing but I can try!...

Could you show me your method step by step so I'll know how to use a proper method please
1)You only want x's on one side of the equation so take away the smallest value of x's from both sides of the equation, in this cast is is 2x. If one of the values in front of the x's was negative, you would add that number of x's to both sides.
This leaves you with 4x-5=13
2)Now you only want numbers on one side of the equation. To get rid of a number on one side of an equation you need to add that number to both sides if the number you want to get red of is negative or take away if it is positive. In this case we would want to get rid of the -5, therefore we add 5 to both sides. (since -5+5=0)
This leaves you with 4x=18
3) You now know what 4x is equal to. Therefore, to get x we divide both sides by 4 (because 4x/4 is x)
This leaves you with x=18/4
4) Simplify the fraction to get x=18/4 which also equals 9/2 or you could write this as 4.5
Hope it helps, sorry if it doesn't (I'm not great at explaining things!).
