Answer:
The value of x in terms of b is: 
The value of x when b is 3 is: x = -1
Step-by-step explanation:
We are given the function: 
First we need to find
The value of x in terms of b
We need to find value of x

Multiply -2 with terms inside the bracket

Subtract 10 from both sides

Divide both sides by -2b

So, The value of x in terms of b is: 
The value of x when b is 3
We have the equation for the value of x in terms of b:

Put b = 3

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