The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move the summands with the unknown n
from the right part to the left part:
$$- \frac{38 n}{5} = 0$$
Divide both parts of the equation by -38/5
We get the answer: n = 0
-2*n = (28/5)*n
Expand brackets in the right part
-2*n = 28/5n
Move the summands with the unknown n
from the right part to the left part:
$$- \frac{38 n}{5} = 0$$
Divide both parts of the equation by -38/5
n = 0 / (-38/5)
We get the answer: n = 0
