Question

Solve each equation. 8(3b + 1) = 4(b + 3) - 9 b 4 O a. - - - Ob- Och Od. 4 2

Answer 1

`8(3b+1)=4(b+3)-9`
`\begin{gathered} 24b+8=4b+12-9 \\ \end{gathered}`

subtract 4b from both sides

`24b-4b+8=4b-4b+3`
`20b+8=3`

subtract 8 from both sides

`20b+8-8=3-8`
`20b=-5`

divide both sides by 20

`\begin{gathered} (20b)/(20)=(-5)/(20) \\ b=-(1)/(4) \end{gathered}`
