The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 4 x + 132$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = 132$$
Divide both parts of the equation by -11
We get the answer: x = -12
-18-7*x = 114+4*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 4 x + 132$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = 132$$
Divide both parts of the equation by -11
x = 132 / (-11)
We get the answer: x = -12
