The solution
Detail solution
Given the equation:
$$\frac{3 - x}{5 x + 6} = 0$$
Multiply the equation sides by the denominator 6 + 5*x
we get:
$$3 - x = 0$$
Move free summands (without x)
from left part to right part, we given:
$$- x = -3$$
Divide both parts of the equation by -1
We get the answer: x = 3
$$\frac{3 - x}{5 x + 6} = 0$$
Multiply the equation sides by the denominator 6 + 5*x
we get:
$$3 - x = 0$$
Move free summands (without x)
from left part to right part, we given:
$$- x = -3$$
Divide both parts of the equation by -1
x = -3 / (-1)
We get the answer: x = 3
