Evaluate the expression 4b - 3b + 2 when b = 5.

Explanation:
When you see 4b - 3b + 2, start by combining like terms with b. 4b and -3b combine to (4 - 3)b = b, so the expression simplifies to b + 2. Then substitute b = 5: 5 + 2 = 7. So the value is 7. (You can also plug in first: 4(5) - 3(5) + 2 = 20 - 15 + 2 = 7.)
