The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 9 x = 8 - 8 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 8$$
Divide both parts of the equation by -1
We get the answer: x = -8
-9*x-8 = -8*x
Move free summands (without x)
from left part to right part, we given:
$$- 9 x = 8 - 8 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 8$$
Divide both parts of the equation by -1
x = 8 / (-1)
We get the answer: x = -8
