The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$4 x = x - 24$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -24$$
Divide both parts of the equation by 3
We get the answer: x = -8
4*(x+6) = x
Expand brackets in the left part
4*x+4*6 = x
Move free summands (without x)
from left part to right part, we given:
$$4 x = x - 24$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -24$$
Divide both parts of the equation by 3
x = -24 / (3)
We get the answer: x = -8
