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:
$$2 x = 2 x + 8$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 8$$
This equation has no roots
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:
$$2 x = 2 x + 8$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 8$$
This equation has no roots
