$$\left(\frac{x + 1300}{2} + \left(\left(x + x\right) + 1300\right)\right) + 600 = 23000$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{2} = 20450$$
Divide both parts of the equation by 5/2
We get the answer: x = 8180
x+x+1300+(x+1300)/2+600 = 23000
Expand brackets in the left part
x+x+1300+x/2+1300/2+600 = 23000
Looking for similar summands in the left part:
2550 + 5*x/2 = 23000
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{2} = 20450$$
Divide both parts of the equation by 5/2
x = 20450 / (5/2)
We get the answer: x = 8180
