The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 10 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 9$$
Divide both parts of the equation by -1
We get the answer: x = -9
-5+9*x = 10*x+4
Move free summands (without x)
from left part to right part, we given:
$$9 x = 10 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 9$$
Divide both parts of the equation by -1
x = 9 / (-1)
We get the answer: x = -9
