Answer:
a. 12a + 3b
b. 5b + 3a
Step-by-step explanation:
Which terms have the same thing applied to them? This is what I ask myself while figuring these out.
a. 5 and 7 both are multiplied by a, so you can combine the expressions to make 12a.
b. 10b - 5b = (10 - 5)b
Both 10 and 5 are multiplied by b, so you can just subtract the integers to get 5b.
I hope this helped!
