Why the strange typing, when you end up with the proper version at the end of each question anyway?
Your question fixed:
a) Simplify the expression and explain each step. (2 points)
12+3(2y - 3)
b) Factor the expression completely. (1 point)
18b - 12

a) 12 + 3(2y - 3)
= 12 + 6y - 9
= 6y + 3 , it did not say factor, but you could do it

b) 18b - 12
= 6(3b - 2)
