The solution
Detail solution
Given the equation:
$$\frac{x + 3}{x - 3} = -1$$
Multiply the equation sides by the denominator -3 + x
we get:
$$x + 3 = 3 - x$$
Move free summands (without x)
from left part to right part, we given:
$$x = - x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 0$$
Divide both parts of the equation by 2
We get the answer: x = 0
$$\frac{x + 3}{x - 3} = -1$$
Multiply the equation sides by the denominator -3 + x
we get:
$$x + 3 = 3 - x$$
Move free summands (without x)
from left part to right part, we given:
$$x = - x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 0$$
Divide both parts of the equation by 2
x = 0 / (2)
We get the answer: x = 0
