The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 3 x - 99$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = -99$$
Divide both parts of the equation by -9
We get the answer: x = 11
86-6*x = 3*x-13
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 3 x - 99$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = -99$$
Divide both parts of the equation by -9
x = -99 / (-9)
We get the answer: x = 11
