Chapter 8: Q15. (page 410)

Tell whether the ordered pair is a solution of the equation.
$3 x - 5 y = - 1; (9, 5)$

Short Answer

Expert verified

The ordered pair $(9, 5)$ isnot a solution for the given equation.

Step by step solution

Step 1. Given information.

The given equation is $x - 2 y = 8$ .

Step 2. Calculation.

To check whether the ordered pair $(9, 5)$ is a solution for the given equation or not, we will substitute coordinates of point $(9, 5)$ in our given equation as shown below:

$\begin{matrix} 3 x 鈭� 5 y = 鈭� 1 (Givenequation) \\ 3 (9) 鈭� 5 (5) = 鈭� 1 (Substituting x = 9 and y = 5) \\ 27 鈭� 25 = 鈭� 1 \\ 2 = 鈭� 1 \end{matrix}$

Since both sides of equation are equal, therefore, the ordered pair $(9, 5)$ is a solution for the given equation.

Step 3. Conclusion.

The given point is not the solution of the given equation.
