The solution
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:
$$2 x = 1$$
Divide both parts of the equation by 2
We get the answer: x = 1/2
(x+1)+(x+3) = 5
Expand brackets in the left part
x+1+x+3 = 5
Looking for similar summands in the left part:
4 + 2*x = 5
Move free summands (without x)
from left part to right part, we given:
$$2 x = 1$$
Divide both parts of the equation by 2
x = 1 / (2)
We get the answer: x = 1/2
