The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 4 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 4$$
Divide both parts of the equation by -10
We get the answer: x = -2/5
-4-6*x = 4*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 4 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 4$$
Divide both parts of the equation by -10
x = 4 / (-10)
We get the answer: x = -2/5
