Chapter 8: Q3. (page 407)

Tell whether the ordered pair is a solution of $3 x + 2 y = - 8$ .
$(4, - 12)$

Short Answer

Expert verified

The ordered pair $(4, - 12)$ is not a solution for the given equation.

Step by step solution

Step 1. Given Information.

An equation: $3 x + 2 y = - 8$

Step 2. Calculation.

To check whether the ordered pair $(4, - 12)$ is a solution for the given equation or not, we will substitute coordinates of point $(4, - 12)$ in our given equation as shown below:

\begin{matrix} 3 x + 2 y = - 8 (Givenequation) \\ 3 (4) + 2 (- 12) = - 8 (Substituting x = 4 and y = - 12) \\ 12 - 24 = - 8 \\ - 12 \neq - 8 \end{matrix}

Step 3. Conclusion.

Since both sides of equation are not equal, therefore, the ordered pair $(4, - 12)$ is not a solution for the given equation.
