The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 8 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 8$$
Divide both parts of the equation by 4
We get the answer: x = 2
2*x+5 = 2*(-x+1)+11
Expand brackets in the right part
2*x+5 = -2*x+2*1+11
Looking for similar summands in the right part:
5 + 2*x = 13 - 2*x
Move free summands (without x)
from left part to right part, we given:
$$2 x = 8 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 8$$
Divide both parts of the equation by 4
x = 8 / (4)
We get the answer: x = 2
