The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 6$$
Divide both parts of the equation by -8
We get the answer: x = -3/4
sqrt(9)-8*x = 9
Expand brackets in the left part
sqrt9-8*x = 9
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 6$$
Divide both parts of the equation by -8
x = 6 / (-8)
We get the answer: x = -3/4
