Chapter 8: Q31. (page 406)

Tell whether the given value of the variable is a solution of the equation.
$x + 11 = 3; x = - 8$

Short Answer

Expert verified

Yes, $x = - 8$ is a solution for the given equation.

Step by step solution

Step 1. Given Information.

An equation: $x + 11 = 3$

Step 2. Calculation.

To check whether $x = - 8$ is a solution for the given equation or not, we will substitute $x = - 8$ in our given equation as shown below:

$\begin{matrix} x + 11 = 3 (Givenequation) \\ - 8 + 11 = 3 (Substituting x = - 8) \\ 3 = 3 \end{matrix}$

Step 3. Conclusion.

Since both sides of equation are equal, therefore, $x = - 8$ is a solution for the given equation.
