The solution
Detail solution
Given the linear equation:
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
2*x = 4*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
