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:
$$0 = x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -5$$
Divide both parts of the equation by -1
We get the answer: x = 5
5 = 4*x-3*x
Looking for similar summands in the right part:
5 = x
Move free summands (without x)
from left part to right part, we given:
$$0 = x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -5$$
Divide both parts of the equation by -1
x = -5 / (-1)
We get the answer: x = 5
