Solve each equation. State any extraneous solutions.
$\frac{j}{j + 2} = \frac{j 鈭� 6}{j 鈭� 2}$

Short Answer

Expert verified

The solution of the equation is $鈭� 6$

Step by step solution

Step 1. State the concept for observational studies.

The linear equations in one variable is an equation which is expressed in the form of $a x + b = 0$ , where a and b are two integers, and x is a variable and has only one solution.

Step 2. Solve the equation.

The equation can be solved as follows:

$\begin{matrix} \frac{j}{j + 2} = \frac{j 鈭� 6}{j 鈭� 2} \\ j (j 鈭� 2) = (j + 2) (j 鈭� 6) \\ j^{2} 鈭� 2 j = j (j 鈭� 6) + 2 (j 鈭� 6) \\ j^{2} 鈭� 2 j = j^{2} 鈭� 6 j + 2 j 鈭� 12 \\ 鈭� 2 j = 鈭� 4 j 鈭� 12 \\ 鈭� 2 j + 4 j = 鈭� 12 \\ 2 j = 鈭� 12 \\ \frac{2 j}{2} = \frac{鈭� 12}{2} \\ j = 鈭� 6 \end{matrix}$

Step 3. Check the solution.

To check the solution, substitute $j = 鈭� 6$ for in the original equation,

$\begin{matrix} \frac{j}{j + 2} = \frac{j 鈭� 6}{j 鈭� 2} \\ \frac{(鈭� 6)}{(鈭� 6) + 2} = \frac{(鈭� 6) 鈭� 6}{(鈭� 6) 鈭� 2} \\ \frac{鈭� 6}{鈭� 4} = \frac{鈭� 12}{鈭� 8} \\ \frac{3}{2} = \frac{3}{2} \\ L H S = R H S \end{matrix}$

Since both sides are equal, the equation is correct.
