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:
$$6 x = 4$$
Divide both parts of the equation by 6
We get the answer: x = 2/3
(2*x-1)*4-x*2 = 0
Expand brackets in the left part
2*x*4-1*4-x*2 = 0
Looking for similar summands in the left part:
-4 + 6*x = 0
Move free summands (without x)
from left part to right part, we given:
$$6 x = 4$$
Divide both parts of the equation by 6
x = 4 / (6)
We get the answer: x = 2/3
