The solution
Detail solution
Given the equation:
Multiply the equation sides by the denominator 6 + x
we get:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 2 x + 13$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 13$$
This equation has no roots
