Answer: 49
Step-by-step explanation: To evaluate 13 + 6y if y = 6,
we start by substituting 6 in for y.
So we have 13 + 6(6).
Remember to use parentheses when
substituting numbers in for variables.
Now, we use the order of operations to simplify from here.
Since multiplication comes before addition, our next step is
to multiply 6(6) to get 36, and we have 13 + 36, which is 49.
