Answer: b = +4
Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.
So first, let's put our variables together on the left side by subtracting 2b from both sides of the equation. That gives us 4b + 2 = 18.
Now we can move our numbers to the right by subtracting 2 from both sides and we get 4b = 16.
Divide both sides by 4 and b = +4.
