The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = x - 25$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -25$$
Divide both parts of the equation by -5
We get the answer: x = 5
-4*x+22 = x-3
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = x - 25$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -25$$
Divide both parts of the equation by -5
x = -25 / (-5)
We get the answer: x = 5
