Answer 1

Evaluate 6+3b if b=7
To solve this problem, we must plug the value of b into the equation and follow the order of operations like so:
Original Equation: 6+3b
Plug in Given Information: 6+3*7
Remember that in the order of operations, we multiply before adding.
Multiply: 6+21
Add: The answer is 27.

Answer 2

27. Replace b with 7, making 6 + 3(7). The 3 and parentheses of 7 hint multiplication, so you multiply to make 21, then add 6 relating back to PEMDAS to teach you the correct order to solve the problem.
