5a + 10b -2
-3y +7z + 5
In the first problem, the two "b" terms combined; in the second the z's

Since you are learning the property, write out the step:
5a + 7b - 2 + 3b = 5a + b*(7 + 3) -2
=5a + 10b - 2
etc.

5a+7b-2+3b=5a+10b-2 add all like terms(b with b)and get the answer. 6z-3y+z+5=7z-3y+5 same here.

The distributive property for multiplication over addition says that a(b+c) = ab + ac, so:
1. 5a+10b-2
2. 7z-3y+5

#1) 5a+10b-2
#2) -3y+7z+5
(Doing this is not required, but most teachers want the variables to be in alphabetical order.)
