The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 4 x$$
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
20-4*x = 24*x+20-28*x
Looking for similar summands in the right part:
20 - 4*x = 20 - 4*x
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 4 x$$
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
