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
