The solution
Detail solution
Given the linear equation:
Move the summands with the unknown x
from the right part to the left part:
$$- \frac{4 x}{7} = 0$$
Divide both parts of the equation by -4/7
We get the answer: x = 0
-2/7*x = 2/7*x
Move the summands with the unknown x
from the right part to the left part:
$$- \frac{4 x}{7} = 0$$
Divide both parts of the equation by -4/7
x = 0 / (-4/7)
We get the answer: x = 0
