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:
Divide both parts of the equation by 5
We get the answer: x = 11/5
5*(x-4) = -9
Expand brackets in the left part
5*x-5*4 = -9
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 5
x = 11 / (5)
We get the answer: x = 11/5
