Answer: i will give you the first couple answers and how i got it you do the rest yourself. You need to combine like terms so add or subtract only the same numbers with the same sign. if the sign has no number imagine an invisible 1 before it. so for example the first one would be (4A) all i did was add the A together to get that i will also give you the last answer for another example. the problem is 20-9z+4y+7-x. all you gotta do is add 7 to the 20 add -9+-x and leave the 4y alone since there is no other y the answer would be 27-10z+4y+
