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