Chapter 12: Q29. (page 745)

Solve each equation. State any extraneous solutions.
$\frac{3}{c} = \frac{2}{c + 2}$

Short Answer

Expert verified

The solution of the equation is $- 6$ .

Step by step solution

Step 1. State the concept for observational studies.

The linear equation in one variable is an equation which is expressed in the form of $a x + b = 0$ , where localid="1648196958283" $a$ 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:

$\begin{array}{l} \frac{3}{c} = \frac{2}{c + 2} \\ 3 (c + 2) = 2 c \\ 3 c + 6 = 2 c \\ 3 c + 6 - 2 c = 2 c - 2 c \\ c + 6 = 0 \\ c = - 6 \end{array}$

Step 3. Check the solution.

To check the solution, substitute $c = 6$ for in the original equation,

$\frac{3}{c} = \frac{2}{c + 2} \frac{3}{(- 6)} = \frac{2}{(- 6) + 2} - 2 = \frac{2}{- 4} - 2 = - 2 L H S = R H S$

Since both sides are equal, the equation is correct.
