Question

For the given equation, enter the value of B when x= - 1/5B/x =20

Answer 1

`B=4`

Explanation:

To solve the following equation.

`\begin{gathered} (B)/(x)=20 \\ \end{gathered}`

Substitute x=-1/5, and use inverse operations to solve equations.

*Addition and subtraction are inverse operations, multiplication, and division too.

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