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:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 4
We get the answer: x = -1
2*(4+x) = 4-2*x
Expand brackets in the left part
2*4+2*x = 4-2*x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 4
x = -4 / (4)
We get the answer: x = -1
