The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$8 x = - 2 x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -12$$
Divide both parts of the equation by 10
We get the answer: x = -6/5
7+8*x = -2*x-5
Move free summands (without x)
from left part to right part, we given:
$$8 x = - 2 x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -12$$
Divide both parts of the equation by 10
x = -12 / (10)
We get the answer: x = -6/5
