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