The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = x$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 0$$
This equation is the identity and the solution: any x
x+20 = 20+x
Move free summands (without x)
from left part to right part, we given:
$$x = x$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 0$$
This equation is the identity and the solution: any x
