The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -4$$
Divide both parts of the equation by 2
We get the answer: x = -2
3*x-7 = x-11
Move free summands (without x)
from left part to right part, we given:
$$3 x = x - 4$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = -4$$
Divide both parts of the equation by 2
x = -4 / (2)
We get the answer: x = -2
