The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -12$$
Divide both parts of the equation by 6
We get the answer: x = -2
7*x-4 = x-16
Move free summands (without x)
from left part to right part, we given:
$$7 x = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -12$$
Divide both parts of the equation by 6
x = -12 / (6)
We get the answer: x = -2
