The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands 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 5
We get the answer: x = 3
3*x-11 = 6*x-4*(2*x-1)
Expand brackets in the right part
3*x-11 = 6*x-4*2*x+4*1
Looking for similar summands in the right part:
-11 + 3*x = 4 - 2*x
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 5
x = 15 / (5)
We get the answer: x = 3
