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:
$$- 5 x = - 5 x$$
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
4-5*(x-1) = 9-5*x
Expand brackets in the left part
4-5*x+5*1 = 9-5*x
Looking for similar summands in the left part:
9 - 5*x = 9-5*x
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 5 x$$
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
