wait this is even simplier they just want you to add like terms

- anonymous

you need to simplify the equation by combining elements with the same variable. if it's just a letter, it's 1*the variable. You also combine numbers.

Does that help?

i dont know

ok i understand that but i dont understand how to simplify it all down to where i can find the answer

- BunnyKitten02

if that makes sense

- triciaal

you have to read the responses.
what is 2 - 20-10 =

- BunnyKitten02

is it -28

- triciaal

what is -28*n^2

- BunnyKitten02

what is n
is it a certain number

- triciaal

no

- BunnyKitten02

so what is it for

- triciaal

in algebra we use letters and numbers
just an entity

- BunnyKitten02

so do i just ignore it

- triciaal

it exists you can't just ignore it

- BunnyKitten02

so what do you do with it

- BunnyKitten02

- triciaal

do you see all we did was group like terms and simplify?

- BunnyKitten02

i guess so.
i feel soooooo stupid right now

- triciaal

don't. you just need to try.

- BunnyKitten02

but i have it just doesnt ever seem to work

- triciaal

clear the negative things from your mind and you will have room to absorb the new material more easily.

- triciaal

you are here to learn and we cannot give direct answers. you need to read the responses given and ask questions about what you do not understand.

- BunnyKitten02

ok
so how can i solve these quickly because this is due soon

- triciaal

once you learn something practice and you will be able to do the problems faster. this is basic stuff for higher math.
all the best.

- triciaal

for now just look at what the question is asking and identify what needs to be done
seems like all you are doing right now is grouping like terms

- BunnyKitten02

i have like 15 minutes

- BunnyKitten02

and like 6 or 7 questions left

- triciaal

well don't panic do 4 right and mark the rest if necessary but always mark something
