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
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)
