All sides are the same, so:

4x - 30 = 2x + 20

2x = 50

x = 25

I believe x=25. If you look at the sides and what x is multiplied by. You could see that 2x+20 would be one side, which means 50+20 is that side so 70. then 3x-5 would be 70. and so on. You can understand from there on out.

Hope this helps.
