The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 6/7
We get the answer: x = 14
x-11 = (x+7)/7
Expand brackets in the right part
x-11 = x/7+7/7
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 6/7
x = 12 / (6/7)
We get the answer: x = 14
