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.
