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