The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 6 x + 36$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = 36$$
Divide both parts of the equation by -9
We get the answer: x = -4
-3*x-18 = 6*x+18
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 6 x + 36$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = 36$$
Divide both parts of the equation by -9
x = 36 / (-9)
We get the answer: x = -4
