The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{x}{2} + 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{x}{2} = 3$$
Divide both parts of the equation by 1/2
We get the answer: x = 6
x-4/4-2 = x/2
Looking for similar summands in the left part:
-3 + x = x/2
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{x}{2} + 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{x}{2} = 3$$
Divide both parts of the equation by 1/2
x = 3 / (1/2)
We get the answer: x = 6
