The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 3 x - 88$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -88$$
Divide both parts of the equation by -11
We get the answer: x = 8
-8*x-17 = 3*x-105
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 3 x - 88$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -88$$
Divide both parts of the equation by -11
x = -88 / (-11)
We get the answer: x = 8
