Question

Do y’all know what b is 7=-11+3(b+5)

Answer 1

`7=-11+3(b+5)`

Solve for b:

Expand the right hand side using distributive property:

`7=-11+3b+15`

Add like terms:

`7=3b+4`

Subtract 4 from both sides:

`\begin{gathered} 7-4=3b+4-4 \\ 3=3b \end{gathered}`

Divide both sides by 3:

`\begin{gathered} (3)/(3)=(3b)/(3) \\ b=1 \end{gathered}`
