The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 20 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 20$$
Divide both parts of the equation by -5
We get the answer: x = -4
-6*x+2 = -x+22
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 20 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = 20$$
Divide both parts of the equation by -5
x = 20 / (-5)
We get the answer: x = -4
