The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 36 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-6\right) x = 36$$
Divide both parts of the equation by -6
We get the answer: x = -6
-8*x+4 = -2*x+40
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 36 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-6\right) x = 36$$
Divide both parts of the equation by -6
x = 36 / (-6)
We get the answer: x = -6
