Question

Solve the equation. Check your solution.

$a-5=8$

Short answer

Solution of given equation is$a=13$.

Step-by-step solution

Step 1.  Solving for value of a

$a-5=8$

Adding $5$on both sides, we get

$\begin{array}{c}a-5+5=8+5\\ a=8+5\\ a=13\end{array}$

$a=13$

Step 2. Verification of our solution

For checking our answer, substitute $a=13$ in given equation $a-5=8$.

On substituting, we get

$\begin{array}{c}a-5=8\\ 13-5=8\\ 8=8\end{array}$

Step 3.  Conclusion

Here, as both sides above expression are equal, our answer is true.
