please

[limber oxide]

🥺

its not 10x + 21

ah

12x + 15 - 2x - 3

10x + 12

or

?

[plush flicker]

it's supposed to be 12x+15-2x-6

because 3(4x+5) is 12x+15

[limber oxide]

ah my bad my bad

• -2 x 3 = -6

my bad bro

[plush flicker]

yeah you're right

it should be 10x+9

[limber oxide]

Wb this

[plush flicker]

same method

2(x+4)

[limber oxide]

2x + 8 - 6x - 3

i thought it was -4x + 5

cuz

2x - 6x = -4x

8 - 3 = 5

[plush flicker]

nah separate the brackets

do 2(x+4) first

which is 2x+8 right?

then do 3(2x-1)

[limber oxide]

wait

im confused there

[plush flicker]

basically what i did was expand the 3(2x-1) as if it was to be positive

and then i changed it to negative by switching the signs

6x would then be -6x

-3 would then be 3

[limber oxide]

so whats the answer

@plush flicker

[plush flicker]

what is 2(x+3)

@limber oxide

[limber oxide]

2x + 6

[plush flicker]

what about 3(2x-5)?

[limber oxide]

6x-15

-6x-15

[plush flicker]

yeah 6x-15

but you need to flip the signs so it will be

-6x+15

2x+6-6x+15

[limber oxide]

ok

then

hmm

QUICKJ

ee

2d

-4x + 21?

[plush flicker]

yup @limber oxide

[limber oxide]

its wrong
