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

Answer 1

The first step is to isolate the variable x by undoing any addition or subtraction operations performed on it. In this case, we have to undo the -4.

Adding 4 to both sides of the equation, we get:

20 + 4 = 6x - 4 + 4

Simplifying both sides:

24 = 6x

Now, we can move to the next step to solve for x.
