To solve for all values of x, we first need to set up the equation:
x - (3x + 5)/(x + 2) = 1/(x + 2)
Now we simplify the left side of the equation:
x - (3x + 5)/(x + 2) = 1/(x + 2)
x - (3x + 5)/(x + 2) = 1/(x + 2)
Multiplying through by (x + 2):
(x)(x + 2) - (3x + 5) = 1
Expanding:
x^2 + 2x - 3x - 5 = 1
x^2 - x - 5 = 1
x^2 - x - 6 = 0
Now we have a quadratic equation that we can solve for x:
(x - 3)(x + 2) = 0
x - 3 = 0 or x + 2 = 0
x = 3 or x = -2
Therefore, the values of x that satisfy the equation are x = 3 and x = -2.
x - (3x + 5)/(x + 2) = 1/(x + 2)
Now we simplify the left side of the equation:
x - (3x + 5)/(x + 2) = 1/(x + 2)
x - (3x + 5)/(x + 2) = 1/(x + 2)
Multiplying through by (x + 2):
(x)(x + 2) - (3x + 5) = 1
Expanding:
x^2 + 2x - 3x - 5 = 1
x^2 - x - 5 = 1
x^2 - x - 6 = 0
Now we have a quadratic equation that we can solve for x:
(x - 3)(x + 2) = 0
x - 3 = 0 or x + 2 = 0
x = 3 or x = -2
Therefore, the values of x that satisfy the equation are x = 3 and x = -2.

Checking for potential division by zero:
When x = -2, the denominator of both fractions becomes zero.
Therefore, x = -2 is not a valid solution and it should be excluded.
The only valid solution is x = 3.

Therefore, x = -2 is not a valid solution and it should be excluded.
