Chapter 8: Q34. (page 406)

Tell whether the given value of the variable is a solution of the equation.
$\frac{- 144}{u} = 12; u = - 12$

Short Answer

Expert verified

Yes, $u = - 12$ is a solution for the given equation.

Step by step solution

Step 1. Given Information.

An equation: $\frac{- 144}{u} = 12$

Step 2. Calculation.

To check whether $u = - 12$ is a solution for the given equation or not, we will substitute $u = - 12$ in our given equation as shown below:

\begin{matrix} \frac{- 144}{u} = 12 (Givenequation) \\ \frac{- 144}{- 12} = 12 (Substituting u = - 12) \\ \frac{- 12 \cdot 12}{- 12} = 12 \\ 12 = 12 (Usingproperty \frac{(-)}{(-)} = (+)) \end{matrix}

Step 3. Conclusion.

Since both sides of equation are equal, therefore, $u = - 12$ is a solution for the given equation.
