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

To solve the equation 20 = 6x - 4, the first step is to isolate the variable term, 6x.

Adding 4 to both sides of the equation gives:
20 + 4 = 6x
Simplifying the equation:
24 = 6x
Now, the equation is in the form of ax = b, where a = 6 and b = 24.
