The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = 13$$
Divide both parts of the equation by 4
We get the answer: x = 13/4
4*x-5 = 8
Move free summands (without x)
from left part to right part, we given:
$$4 x = 13$$
Divide both parts of the equation by 4
x = 13 / (4)
We get the answer: x = 13/4
