Question

Solve for b: 2b-9=d please I need help

Answer 1

Short answer, we need a value for d, longer answer is
`b = (d)/(2) + 4.5` (I think)

Explanation:

[1] Find b:

2b-9=d

[2] First we need to get b alone:

-
`(b-9)/(2)`=
`(d)/(2)`

-
`b - 4.5 = (d)/(2)`

[3] Then continue

- Add 4.5 to both sides

-
`b = (d)/(2) + 4.5`
