Answer:

The value of x in terms of b is: \mathbf{x=-\frac{6}{2b}}

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: -2(bx-5)=16

First we need to find

The value of x in terms of b

We need to find value of x

-2(bx-5)=16

Multiply -2 with terms inside the bracket

-2bx+10=16

Subtract 10 from both sides

-2bx+10-10=16-10\\-2bx=6

Divide both sides by -2b

\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}

So, The value of x in terms of b is: \mathbf{x=-\frac{6}{2b}}

The value of x when b is 3

We have the equation for the value of x in terms of b:

\mathbf{x=-\frac{6}{2b}}

Put b = 3

x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1

So, The value of x when b is 3 is: x = -1
