Answer:
Step-by-step explanation:
Change the things in the negative parentheses.
Take away parentheses. (Two negative turn into positive.)
Count the numbers by themselves and the letters by themselves.
Then we have
(6y + 10) - (2y + 3)
6y + 10 - 2y - 3
4y + 7
9
-12(3 - 5)
-12 x 3 + - 5 x -12
-36 + 60 = 24
