Explanation:
Alright, so let's start solving this
1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.
How to do that?
Well, we can take -3x and 20 to their other sides.
The reason for this is that we don't want to have the value with x as a negative
So we do
-3x-4 = 20
+3x -20 -20+3x
You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation
-24 = 3x or 3x = -24
Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3
So
3x/3 = -24/3
Which results in x = -8 and voila, there is your answer!
