3x +3y = 3 y = (-1/2)x +2 3x +3y =3 - in case of this equation what can you factorize out - what is common in every term in the left side ? after you factorize it out so you can divide both sides by this number

jhonyy9:

@Laylalyssa any idea ?

Laylalyssa:

3x+3y=3 3x+3y+−3y=3+−3y right

jhonyy9:

no 3(x +y) = 3 divide both sides by 3 and get x +y = 1

Laylalyssa:

I thought it would be -y

jhonyy9:

in this way you can graph it more easy

Laylalyssa:

oh

jhonyy9:

y = (-1/2)x +2 and solve it for y

Laylalyssa:

y= -1/2x+2 ?

Ari1234442:

They are not here

Ari1234442:

Just an FYI

supie:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Laylalyssa y= -1/2x+2 ? \(\color{#0cbb34}{\text{End of Quote}}\) I think he is saying to solve \(y = (-1/2)x +2 \) for \(y\) \(\frac{−1}{2}x+2=y\) \(\sf +2\ to\ both\ sides\) \(\frac{−1}{2}x+2+−2=y+−2\) \(\frac{−1}{2}x=y−2\) \(\sf ÷\frac{(-1)}{2}\ to\ both\ sides\) \(−1/2\ x/-1/2=y−2/−1/2\) \(x=−2y+4\) The graph:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Ari1234442 Yes and who watches the owl house \(\color{#0cbb34}{\text{End of Quote}}\) \(\color{#0cbb34}{\text{Originally Posted by}}\) @supie Stop spamming the post this post is here so we can answer this question now about `Owl House` Please keep the post on topic. \(\color{#0cbb34}{\text{End of Quote}}\)

jhonyy9:

x +y = 1 y = (-1/2)x +2 and now just solve this system

jhonyy9:

bc. you need to find the y coordinate of the system so just substitute the x value from the first equation in place of x inside second equation and in this way will get easy right the y value

jhonyy9:

ok ?

jhonyy9:

x +y = 1 => x = 1 -y y = (-1/2)x +2 y = (-1/2)(1 -y ) +2

jhonyy9:

solve this for y

supie:

We are solving \(y = (-1/2)(1 -y ) +2\) for \(\mathbb y\)?

jhonyy9:

2y = -1 +y +4 y = 3 yes

supie:

Why does \(\sf y=3\)?

jhonyy9:

why not is y=3 ?

Ari1234442:

It is 3 I sloved it

jhonyy9:

congrats @Ari1234442

Ari1234442:

solved it I mean

Ari1234442:

Thanks

jhonyy9:

@supie ok clearly ?

jhonyy9:

@Laylalyssa ?

supie:

Yes.

Laylalyssa:

ye

jhonyy9:

questions ?

Laylalyssa:

no

supie:

Nope.

jhonyy9:

ok bye bye

Ari1234442:

What about the person who asked the question

jhonyy9:

about who talk ?

jhonyy9:

@sddqdqd

Laylalyssa:

the person who asked the question will come back and see it
