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:
$$- 6 x = 2 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = -2$$
Divide both parts of the equation by -8
We get the answer: x = 1/4
4-(6*x+2) = 2*x
Expand brackets in the left part
4-6*x-2 = 2*x
Looking for similar summands in the left part:
2 - 6*x = 2*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 2 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = -2$$
Divide both parts of the equation by -8
x = -2 / (-8)
We get the answer: x = 1/4
