The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 9 x - 13$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -13$$
Divide both parts of the equation by 5
We get the answer: x = -13/5
9-4*x = -9*x-4
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = - 9 x - 13$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -13$$
Divide both parts of the equation by 5
x = -13 / (5)
We get the answer: x = -13/5
