Question

Solve the equation. Check your solution.

$-r=38$

Short answer

Solution of given equation is $r=-38$.

Step-by-step solution

Step-1- Solve the equation for r

$-r=38$

Multiplying with $-1$on both sides, we get

$\begin{array}{c}-r\times \left(-1\right)=38\times \left(-1\right)\\ r=-38\end{array}$

Step-2-Verification of our solution

For checking our answer, substitute $r=-38$in given equation $-r=38$.

On substituting, we get

$\begin{array}{c}-r=38\\ -(-38)=38\\ 38=38\end{array}$

Step-3- Conclusion

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