What is the value of 2b + 5 when b = −3?

Explanation:
Evaluating the expression means substituting the given value into the expression and following the order of operations: multiply before adding. With b = -3, first compute 2 × (-3) = -6. Then add 5: -6 + 5 = -1. So the value is -1. This result comes directly from doubling the negative three and then increasing by five.
