Question

Are these the right steps for simplifying this equation: 4(3p + 1) + 3(p − 1)

Steps:
1) 12p + 1 + 3p − 1 using distributive property of addition
2) 12p + 3p + 1 + 1 simplifying
3) (12 + 3) p + 1 + 1 using commutative property of addition
4) 15p + 2 simplifying

Answer 1

No. 4(3p+1)=12p+4 and
3(p-1)=3p-3

Answer 2

what about
1) 4 (3p) + 4 (1) + 3 (p) + 3 (−1) using distributive property of addition
2) 12p + 4 + 3p − 3 simplifying
3) 12p + 3p + 4 − 3 using commutative property of addition
4) (12 + 3) p + 1 using distributive property of addition
5) 15p + 1 simplifying

Answer 3

Good job!!
