Short Answer

Expert verified

Solution of given equation isy=-9

Step by step solution

01

Step 1.  Solving for value of y

y+9=0

Subtracting 9on both sides, we get

y+9鈭�9=0鈭�9y=0鈭�9y=鈭�9

y=-9

02

Step 2. Verification of our solution

For checking our answer, substitute y=-9 in given equation y+9=0.

On substituting, we get

y+9=0鈭�9+9=00=0

03

Step 3.  Conclusion

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