Question

Solve the equation. Check your solution

$-7=y+13$

Short answer

Solution is$y=-20$.

Step-by-step solution

Step-1- Solving for value of y 

$-7=y+13$

Subtracting$13$on both sides, we get

$\begin{array}{c}-7-13=y+13-13\\ -7-13=y\\ y=-20\end{array}$

Step-2- Verification of our solution 

For checking our answer, substitute $y=-20$in given equation $-7=y+13$.

$\begin{array}{c}-7=-20+13\\ -7=-7\end{array}$

Step-3- Conclusion

Here, as both sides of above expression are equal, it means answer is correct.
