Answer: [tex]12p-2[/tex] (I'm assuming the "?" is a typo?)
Step-by-step explanation:
[tex](7p +18p-14p-5) + (p+3)\\(25p-14p-5)+(p+3)\\(11p-5)+(p+3)\\11p-5+p+3\\12p-2[/tex]
Don't forget we can't add two different variables together (ex. we can't add [tex]1p+3[/tex] together because they're different variables).
The answer is 12p-2 because you add/subtract all of the variables then add/subtract all the numbers that do not have a variable.
