The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$4 x = 27$$
Divide both parts of the equation by 4
We get the answer: x = 27/4
4*(x-8) = -5
Expand brackets in the left part
4*x-4*8 = -5
Move free summands (without x)
from left part to right part, we given:
$$4 x = 27$$
Divide both parts of the equation by 4
x = 27 / (4)
We get the answer: x = 27/4
