The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$2 x = 200$$
Divide both parts of the equation by 2
We get the answer: x = 100
2*(100+x) = 400
Expand brackets in the left part
2*100+2*x = 400
Move free summands (without x)
from left part to right part, we given:
$$2 x = 200$$
Divide both parts of the equation by 2
x = 200 / (2)
We get the answer: x = 100
