Select the correct answer.

Which statement describes the solutions of this equation?
[tex]\frac{2}{x+2} + \frac{1}{10} = \frac{3}{x+3}[/tex]

A. The equation has two valid solutions and no extraneous solutions.
B. The equation has no valid solutions and two extraneous solutions.
C. The equation has one valid solution and no extraneous solutions.
D. The equation has one valid solution and one extraneous solution.



Answer :

To determine the number of valid and extraneous solutions for the equation:

[tex]\[ \frac{2}{x+2} + \frac{1}{10} = \frac{3}{x+3} \][/tex]

we need to perform a series of steps:

1. Identify potential extraneous solutions: These occur when the denominators of fractions become zero, because division by zero is undefined. For this equation, extraneous solutions could occur when [tex]\(x+2 = 0\)[/tex] or [tex]\(x+3 = 0\)[/tex].

So, [tex]\(x = -2\)[/tex] and [tex]\(x = -3\)[/tex] are potential extraneous solutions.

2. Solve the equation: Solving the given equation typically involves finding a common denominator and simplifying the equation to solve for [tex]\(x\)[/tex]. This process will yield potential solutions.

3. Analyze the solutions:
- Check if the solutions are valid: Substituting the solutions back into the equation to ensure they do not cause any denominators to be zero (i.e., they are not [tex]\(x = -2\)[/tex] or [tex]\(x = -3\)[/tex]).
- Check if the solutions are extraneous: Solutions that cause any denominator in the original equation to be zero are extraneous solutions.

After performing the analysis, we find:

- There are two solutions to the equation.
- None of these solutions are extraneous (i.e., neither solution makes the denominators zero).

Thus, the correct statement describing the solutions to the equation is:

A. The equation has two valid solutions and no extraneous solutions.
