This is a simple equation that is easily solved.
2x-4=6 You just have to isolate the variable, which is x, to get the solution.
So what you can do, is to get rid of the -4 to isolate the variable by adding 4 to the other side of the equation.
2x-4 (+4)=6+4
2x=10
Then you can isolate the variable by doing the opposite action it says to do, so division.
x=5
