The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 3 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -4$$
Divide both parts of the equation by -2
We get the answer: x = 2
-5*x+12 = -3*x+8
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 3 x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -4$$
Divide both parts of the equation by -2
x = -4 / (-2)
We get the answer: x = 2
