Question

Determine whether each number is a solution of the given inequality.5b - 7>13

Answer 1

`5b-7>13`

Solve for b:

Add 7 to both sides:

`\begin{gathered} 5b-7+7>13+7 \\ 5b>20 \end{gathered}`

Divide both sides by 5:

`\begin{gathered} (5b)/(5)>(20)/(5) \\ b>4 \end{gathered}`

Answer:

b > 4
