Error Analysis Describe and correct the error in solving $x + 8 = 10$ .

Short Answer

Expert verified

There is an error in the step $x + 8 - 8 = 0 = 10 + 8$ .

And the correction is $x + 8 - 8 = 0 = 10 - 8$ .

Step by step solution

Step 1. Solving given equation

Given equation is,

$x + 8 = 10$ .

Here, we need to subtract $8$ on both sides to get value of $x$ .

$\begin{matrix} x + 8 = 10 \\ x + 8 - 8 = 10 - 8 \\ x = 10 - 8 \\ x = 2 \end{matrix}$

Step 2. Comparing our steps with given steps

On comparing these steps with given steps, we can say that,

$x + 8 - 8 = 10 + 8$ is the wrong step.

Step 3. Conclusion

There incorrect step is $x + 8 - 8 = 10 + 8$ .
