First you would distribute the 3. So it would be (3x+6)+14+7x. Since you can’t do anything inside the parentheses, you drop them. Then you’d combine like terms. 3x+7x is 10x, and 14+6 is 20. That would get you your answer, 10x+20
You have 2 apples.
You can get this by subtracting the 3 from the 5 you originally had.
The fourth one.
