Answer 2

I get confused when the plus and minus clash

Answer 3

are the rest correct

Answer 4

A & B are correct.

In C, the (-) sign should be (+) because 12 minus 9 is positive 3.

In D, combine the constants:
8 + 6d - 12
= 6d - 4

In E, combine the terms with variables:
30e + 18 - 8e
= 22e + 18

In F,
15f + 10 - f - 5
= 14f + 5

hope this helps :3
