The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 9 x = 3 x + 132$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-12\right) x = 132$$
Divide both parts of the equation by -12
We get the answer: x = -11
-16-9*x = 116+3*x
Move free summands (without x)
from left part to right part, we given:
$$- 9 x = 3 x + 132$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-12\right) x = 132$$
Divide both parts of the equation by -12
x = 132 / (-12)
We get the answer: x = -11
