solving, simplyfying, what do you want?

[river apex]

solve

ing

[tepid shuttle]

??

solve how?

equal to zero, one?

could you post the original question?

[river apex]

solving using

distributive law

[tepid shuttle]

so simplyfying

[river apex]

yes

[waxen robin]

hint: use the distributive law

[tepid shuttle]

it expands to 8x+8y-5x+5y

[waxen robin]

are you allowed to tell them that?

[river apex]

yes

[tepid shuttle]

because 8x is 8x, 8y is 8y, -5x=-5x, and (-5)(-y)=5y

[tepid shuttle]

(shhh, its not fully simplified)

[river apex]

the subtract sign in the middle is to subtract right

[tepid shuttle]

yes

[river apex]

so its not negative 5

[waxen robin]

it’s almost the same thing, really

[tepid shuttle]

well...

you're subtracting the expression, but you can think of it like +(-5)

[river apex]

ok

is the answer 13x 3y

[waxen robin]

no

[river apex]

how

[waxen robin]

because that isn’t the answer?

[lethal inlet]

Careless mistake

Check your work again

[river apex]

3y 3y

[lethal inlet]

now you're just guessing

[river apex]

how do i do it

[waxen robin]

use the distributive law

what’s 8(x+y) expanded?

[river apex]

i meant 3x 3y

[river apex]

8x 8y

[lethal inlet]

Why don't u have a + sign between the two expressions?

[waxen robin]

8x**+**8y, but yes

now what’s -5(x-y)?

[river apex]

-5x -5y

[lethal inlet]

Well no but try again

You're close

[waxen robin]

not quite

[lethal inlet]

Notice how y has a negative sign

[river apex]

-5x +5y

[waxen robin]

great

[lethal inlet]

W thats correct

[waxen robin]

now what’s 8x+8y-5x+5y?

[river apex]

3x + 13y

[waxen robin]

yep

that’s it

that’s all it is

[lethal inlet]

Bro cooked math

Ws in the chat

[river apex]

type shi

[lethal inlet]

If you're done close the channel

[river apex]

one sec

what is

7(3x+4y) + 3(4x+4y)

[lethal inlet]

Well just use the logic we just used

Try it yourself

[river apex]

i got

33x + 40y

[waxen robin]

checks out

[lethal inlet]

Mhm

[river apex]

wum

wym

[lethal inlet]

You're correct

[river apex]

ok ty

one more

8(7x+3y) +4(5x+2y)

[lethal inlet]

And what'd u get for this one?

[river apex]

76x + 32y

[lethal inlet]

Correcto
