Answer:
Short answer, we need a value for d, longer answer is [tex]b = \frac{d}{2} + 4.5[/tex] (I think)
Step-by-step explanation:
[1] Find b:
2b-9=d
[2] First we need to get b alone:
- [tex]\frac{b-9}{2}[/tex]=[tex]\frac{d}{2}[/tex]
- [tex]b - 4.5 = \frac{d}{2}[/tex]
[3] Then continue
- Add 4.5 to both sides
- [tex]b = \frac{d}{2} + 4.5[/tex]
