Answer: b = 7
Step-by-step explanation: When we have his 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 6b from both sides of the equation.
That gives us b - 3 = 4
Now we can move our numbers to the right by
adding 3 to both sides and we get b = 7.
So we have b = 7 which is the solution to this equation.
