2 things. It must have been centralized because that level of technology requires organization and specialization, so part of the population works in agriculture and the rest is free to research and discover things. The second thing is that it means they were very powerful because these great buildings were not civilian dwellings. The rulers must have had the intimidation to convince the population to pour so much work into construction, often using religion to justify their positions in power.
The answer you are looking for is x = 0 (or undefined)
To solve for x, you would first combine all the like terms on the right side. To do so, add 2x and 2x to get 4x and add 24 and 2 together to get 26. This will give you 4x + 28 = 4x + 26, which you can now solve.
To find x, you would get the x by itself. However, in doing so you would get 0 or 0x. This is because you would subtract 4x on both sides to cancel out the 4x on the right, but in this case, it will also cancel out the 4x on the left. Thus meaning the answer is 0 or undefined.
I hope this helps!
