Question

x-105/x+3=-5 ))))))))))))

Answer 1

Если х=105,то  х+3=-5 = 105+3=-5=103
Если х=-105,то х+3=-5 = -105+3=-5=--107

Answer 2

To solve for x, we need to isolate x on one side of the equation.

First, we can eliminate the fraction by cross-multiplying:

(x-105) * (x+3) = -5 * (x+3)

Expanding the left side:

x^2 - 102x - 315 = -5x - 15

Moving all the terms to one side:

x^2 - 97x - 300 = 0

Now we need to factor this quadratic equation to find the values of x.

We can start by looking for two numbers that multiply to -300 and add up to -97.

After some trial and error, we find that -25 and 12 satisfy these conditions:

(x - 25) * (x + 12) = 0

So the solutions for x are:

x = 25 or x = -12

We can check both of these values in the original equation to make sure they are valid solutions:

For x = 25:

(25-105)/(25+3) = -5

-80/28 = -5

-2.857 = -5 (not true)

For x = -12:

(-12-105)/(-12+3) = -5

-117/-9 = -5

13 = 13 (true)

Therefore, the solution to the equation is x = -12.
