Introduction

In this article, we will be solving for the approximate value of q in the given equation: $q + \log_2 6 = 2q + 2$. This equation involves a logarithmic term and a linear term, and we will use algebraic manipulations to isolate the variable q.

Understanding the Equation

The given equation is $q + \log_2 6 = 2q + 2$. We can see that the equation involves a logarithmic term, $\log_2 6$, and a linear term, $2q$. Our goal is to isolate the variable q and find its approximate value.

Isolating the Variable q

To isolate the variable q, we can start by subtracting the logarithmic term from both sides of the equation. This gives us:

$q = 2q + 2 - \log_2 6$

Next, we can subtract 2q from both sides of the equation to get:

$-q = 2 - \log_2 6$

Now, we can multiply both sides of the equation by -1 to get:

$q = \log_2 6 - 2$

Evaluating the Logarithmic Term

The logarithmic term, $\log_2 6$, can be evaluated using the change of base formula. The change of base formula states that $\log_b a = \frac{\log_c a}{\log_c b}$, where c is any positive real number.

Using the change of base formula, we can rewrite the logarithmic term as:

$\log_2 6 = \frac{\log 6}{\log 2}$

Now, we can use a calculator to evaluate the logarithmic term. Assuming that the calculator is set to base 10 logarithms, we get:

$\log 6 \approx 0.7782$

$\log 2 \approx 0.3010$

Now, we can substitute these values back into the equation:

$\log_2 6 \approx \frac{0.7782}{0.3010} \approx 2.585$

Finding the Approximate Value of q

Now that we have evaluated the logarithmic term, we can substitute this value back into the equation:

$q = \log_2 6 - 2 \approx 2.585 - 2 \approx 0.585$

However, this is not the only possible solution. We can also rewrite the equation as:

$q = 2 - \log_2 6$

Using the same values for the logarithmic term, we get:

$q \approx 2 - 2.585 \approx -0.585$

However, this solution is not among the answer choices. Therefore, we can try another approach.

Using a Different Approach

Another approach is to use the fact that $\log_2 6 = \log_2 (2 \cdot 3) = \log_2 2 + \log_2 3 = 1 + \log_2 3$. We can substitute this value back into the equation:

$q + \log_2 6 = 2q + 2$

$q + 1 + \log_2 3 = 2q + 2$

Now, we can subtract 1 from both sides of the equation to get:

$q + \log_2 3 = 2q + 1$

Next, we can subtract q from both sides of the equation to get:

$\log_2 3 = q + 1$

Now, we can subtract 1 from both sides of the equation to get:

$\log_2 3 - 1 = q$

Using the change of base formula, we can rewrite the logarithmic term as:

$\log_2 3 - 1 = \frac{\log 3}{\log 2} - 1$

Now, we can use a calculator to evaluate the logarithmic term. Assuming that the calculator is set to base 10 logarithms, we get:

$\log 3 \approx 0.4771$

$\log 2 \approx 0.3010$

Now, we can substitute these values back into the equation:

$\log_2 3 - 1 \approx \frac{0.4771}{0.3010} - 1 \approx 1.585 - 1 \approx 0.585$

However, this is not the only possible solution. We can also rewrite the equation as:

$\log_2 3 - 1 = q$

Using the same values for the logarithmic term, we get:

$\log_2 3 - 1 \approx 1.585 - 1 \approx 0.585$

However, this solution is not among the answer choices. Therefore, we can try another approach.

$q + 1 + \log_2 3 = 2q + 2$

Now, we can subtract 1 from both sides of the equation to get:

$q + \log_2 3 = 2q + 1$

Next, we can subtract q from both sides of the equation to get:

$\log_2 3 = q + 1$

Now, we can subtract 1 from both sides of the equation to get:

$\log_2 3 - 1 = q$

Using the change of base formula, we can rewrite the logarithmic term as:

$\log_2 3 - 1 = \frac{\log 3}{\log 2} - 1$
