Cold I get some help combining like terms?

Question

5+10s-8s

6r+3s+2s+4r

xy+2x+x

2(5y-2)+x

5+(4g-7)

I'm not Really that good in math

Answer 1

5 + 2s

10r + 5s

xy + 3x

10y - 4 + x

4g - 2

Answer 2

in the first one you would combine 10s and -8s becasue they are both the same with a number and a letter after it. the 5 has no letter so it is no combined,

the answer would be

5+2S .. you cannot combine the five becasue it does not aheva letter.

answer: 5+2S

number 2.

6r and 4r are combined and 3s and 2s are combined.. leaving you with 10r+6s as your answer.

answer: 10r+6s

number 3. whenever you have just a letter.. you have to pretend there is a one in front of it.. so in this you would combine the X and the 2X creating xy+3x

Answer:xy+3x

number 4/ always start off by distributing.

2 times 5y is 10y

then 2 times -2 is 4 leaving you with 10y-4

(no cimbinging like terms in this one.. it is unnecceasry)

Answer: 10y-4

number 5.

you cannot ditribute bc it is 5+ and not jus 5(

you would combine he 5 and -7 = -2 leaving you with 4g- -2

and when you have a double negative they both turn positive leaving yo uwith 4g+2

Answer: 4g+2

Answer 3

5 - 10s - 8s = 5 - 18s

6r + 3s + 2s + 4r = 10r + 5s

xy + 2x + x = xy + 3x

2(5y - 2) + x = 10y - 4 + x

5 + (4g - 7) = 5 - 7 + 4g = 4g - 2

Answer 4

5 + 2s

10r + 5s

xy + 3x

10y + x - 4

4g - 2

Answer 5

5+2s

10r + 5r

xy + 3x

10y-4+x

20g - 35



I hope this get you outta of a jam but you have to study

=

Answer 6

5+2s

10r+5s

xy+3x

10y-4+x

-2+4g

you just let's say you have 6g+8h+h-7gh,

put circles around everythng with a g next to it, squares around h's, underline gh, and so on.

anything in the same shape gets added/subtracted.

anything left is just added by doing "-7gh" at the end or whatever the case may be, not actually doing the addition.

i hop this helped.

Answer 7

You don't have to be very good at math. Just look at the terms and add the ones that have the same symbol:

1. 5 + 2s

2. 10r + 5s

3. x(y + 3)

etc.

Answer 8

This is pretty much just adding up and taking away

5+2s

6r+4r+3s+2s => 10r+5s

xy+3x

10y-4+x

Why don't you try the last one

edit: the last one is not 20g - .... and it's not 4g+2 either
