Question

Solve the equation. Check your solution.

$r-23=-6$

Short answer

Solution of given equation is$r=17$;

Step-by-step solution

Step 1  .Solving for value of r

$r-23=-6$

Adding23 on both sides, we get

$\begin{array}{c}r-23=-6\\ r-23+23=-6+23\\ r=23-6\\ r=17\end{array}$

$r=17$

.Verification of our solution

For checking our answer, substitute$r=17$ in given equation$r-23=-6$.

On substituting, we get

$\begin{array}{c}r-23=-6\\ 17-23=-6\\ -6=-6\end{array}$

.Conclusion

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