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:
$$12 x = 3 x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 18$$
Divide both parts of the equation by 9
We get the answer: x = 2
3*(4*x-8) = 3*x-6
Expand brackets in the left part
3*4*x-3*8 = 3*x-6
Move free summands (without x)
from left part to right part, we given:
$$12 x = 3 x + 18$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = 18$$
Divide both parts of the equation by 9
x = 18 / (9)
We get the answer: x = 2
