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:
$$- 8 x = - x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -3$$
Divide both parts of the equation by -7
We get the answer: x = 3/7
sqrt(9)-8*x = -x
Expand brackets in the left part
sqrt9-8*x = -x
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = - x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = -3$$
Divide both parts of the equation by -7
x = -3 / (-7)
We get the answer: x = 3/7
