The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = - 9 x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -3$$
Divide both parts of the equation by 10
We get the answer: x = -3/10
x+3 = -9*x
Move free summands (without x)
from left part to right part, we given:
$$x = - 9 x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -3$$
Divide both parts of the equation by 10
x = -3 / (10)
We get the answer: x = -3/10
