The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$0 = 2 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -8$$
Divide both parts of the equation by -2
We get the answer: x = 4
8 = 3*x-x
Looking for similar summands in the right part:
8 = 2*x
Move free summands (without x)
from left part to right part, we given:
$$0 = 2 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -8$$
Divide both parts of the equation by -2
x = -8 / (-2)
We get the answer: x = 4
