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