Question

(7p + 18p? - 14p - 5) + (p+ 3)

Answer 1

Answer: $12p-2$ (I'm assuming the "?" is a typo?)

Step-by-step explanation:

$(7p +18p-14p-5) + (p+3)\\(25p-14p-5)+(p+3)\\(11p-5)+(p+3)\\11p-5+p+3\\12p-2$

Don't forget we can't add two different variables together (ex. we can't add $1p+3$ together because they're different variables).

Answer 2

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.
