Answer:

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

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

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


(-2bx)/(-2b)=(6)/(-2b)\\x=-(6)/(2b)

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

Put b = 3


x=-(6)/(2(3))\\x=-(6)/(6)\\x=-1

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