Question

3+7(p−11)

3+7 x p−7 x ? <-Apply the Distributive Property and multiply.

3+7 x p− ?

7 x p+3− ? <-Apply the Commutative Property of Addition and subtract.

7 x p−74


Answer the question marks in the equations

Answer 1

3+7(p−11) = 3+7p-77 = 7p-74

7 x p−7 x ? = 7p-7x? = 7p-7

7 x p+3− ? = 7p+3-? = 7p+3

So, the answer to the question marks in the equations are:

7p-74 for the first equation

7 for the second equation

?? for the third equation (since the value of "?" is not given)
