Answer: d=-2
Explanation:
As we know the order of operations are
1) Parenthesis/Brackets
2) Exponents
3) Multiplication/Division
4) Addition/Subtraction
However, when you solve equations you must do the order of operations backwards
So start by adding 1 to both sides because whatever you do to one side of the equation you must do to the other side
![5d-1=-11\\5d-1+1=-11+1\\5d=-10](https://img.qammunity.org/2023/formulas/mathematics/high-school/q3prvpho7uscsi48ta2aoqvmwkmvfqpdsm.png)
Now divide both sides by 5 to isolate d
![5d=-10\\(5d)/(5) =(-10)/(5) \\d=-2](https://img.qammunity.org/2023/formulas/mathematics/high-school/tqqus7bpxs7w1n4afpcwsd27xi50e0s3qs.png)
