The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 28 - 6 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 28$$
Divide both parts of the equation by -2
We get the answer: x = -14
-8*x-8 = 20-6*x
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 28 - 6 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 28$$
Divide both parts of the equation by -2
x = 28 / (-2)
We get the answer: x = -14
