Answer: 2b + -6
Step-by-step explanation: To simplify, we will use the distributive property.
Before distributing, I would change the -3 to plus a negative 3.
So we have 2(b + -3).
Now, distributing the 2 through the parenthses, we have 2(b) + 2(-3).
2(b) is 2b and 2(-3) is -6.
So we have 2b + -6 as our final answer.
