The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 2 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -5$$
Divide both parts of the equation by -3
We get the answer: x = 5/3
13-5*x = 8-2*x
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 2 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -5$$
Divide both parts of the equation by -3
x = -5 / (-3)
We get the answer: x = 5/3
