You need to get all of your x's on one side and your numbers on the other. Then, simply divide the sum of the x's by the number on the other side. Your answer will show you what X is.
I suggest moving -5x to the side of -3x to make it positive. 2x.
Then, add 4 to both sides making 8+4 = 12
What is 12 / 2? 6.
X = 6
Lets plug it in.
-3(6) - 4 = -22
8-5(6) = -22
-22 = -22
You get it?

follow step by step
-3x-4=8-5x
-3x+5x=8+4
2x = 12
2x/2 = 12/2
x = 6

add the 5x to the left and the 4 to the right to give 2x=12, then divide each side by 2 to get x=6

1.) transpose -4 & 5x:
-3x+5x=8+4
2.) then do the operations:
2x=12
3.) then divide both equations
by 2 to get the value of x:
x=6
