The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 6 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 4$$
Divide both parts of the equation by -4
We get the answer: x = -1
-8+2*x = 6*x-4
Move free summands (without x)
from left part to right part, we given:
$$2 x = 6 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = 4$$
Divide both parts of the equation by -4
x = 4 / (-4)
We get the answer: x = -1
