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:
Divide both parts of the equation by -7
We get the answer: x = -3/7
11-7*(x+2) = 0
Expand brackets in the left part
11-7*x-7*2 = 0
Looking for similar summands in the left part:
-3 - 7*x = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -7
x = 3 / (-7)
We get the answer: x = -3/7
