add 3y-5 to y+16

3y-5 + y+16

4y + 11

(y+16) + (3y-5)

y + 16 + 3y -5

4y + 11

answer: 4y + 11

To add the expressions 3y - 5 and y + 16, you need to combine like terms. Like terms have the same variable(s) raised to the same power(s). Let's break down the steps to find the sum:

1. Start by combining the terms with the same variable, in this case, the terms with "y". You have 3y and y.

3y + y = 4y

2. Next, combine the constant terms, which are the numbers without variables. In this case, you have -5 and 16.

-5 + 16 = 11

3. Finally, combine the results from steps 1 and 2:

4y + 11

So, the sum of 3y - 5 and y + 16 is 4y + 11.
