The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 4 x + 1$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 1$$
Divide both parts of the equation by -10
We get the answer: x = -1/10
-4-6*x = 4*x-3
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 4 x + 1$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = 1$$
Divide both parts of the equation by -10
x = 1 / (-10)
We get the answer: x = -1/10
