what is the first step in solving the equation 20=6x-4 solving for x

The first step in solving the equation is to isolate the variable x. You can do this by moving all terms not containing x to the other side of the equation.

In this case, you can start by adding 4 to both sides of the equation:

20 + 4 = 6x - 4 + 4

Which simplifies to:

24 = 6x

Now, divide both sides of the equation by 6 to solve for x:

24/6 = (6x)/6

4 = x

Therefore, x = 4.
