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:
$$6 x = 2 x + 20$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 20$$
Divide both parts of the equation by 4
We get the answer: x = 5
6*x-8 = 5*x-3*(x-4)
Expand brackets in the right part
6*x-8 = 5*x-3*x+3*4
Looking for similar summands in the right part:
-8 + 6*x = 12 + 2*x
Move free summands (without x)
from left part to right part, we given:
$$6 x = 2 x + 20$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 20$$
Divide both parts of the equation by 4
x = 20 / (4)
We get the answer: x = 5
