Hi

Rarinstraw and Dessiden.

I am not angry. :)

I am playing a role :))

Welcome to our forum Dessiden :) 

\(4=triangle\)

Melody, please! Do not let your blood boil over this matter.

Solve the following system:

{3 x+y = -1 | (equation 1)

y-3 x = 5 | (equation 2)

Add equation 1 to equation 2:

{3 x+y = -1 | (equation 1)

0 x+2 y = 4 | (equation 2)

Divide equation 2 by 2:

{3 x+y = -1 | (equation 1)

0 x+y = 2 | (equation 2)

Subtract equation 2 from equation 1:

{3 x+0 y = -3 | (equation 1)

0 x+y = 2 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -1 | (equation 1)

0 x+y = 2 | (equation 2)

Collect results:

Answer: |x = -1       and        y=2

where is the picture ?

I already reported it...

Hey Eloise! How've you been?

What?!? It's only 10:00am! Y'all are weirdos...

I'm getting bored here, you guys making all lame jokes, so I will report it and go to a nice website somewhere else.

Let one of the angles be x, then:

2x + 4x + 9x=180

15x=180

x=12, so the angles are:

24, 48, 108 degrees

Coldplay I think you have to be 16 or older without parents permission. By the way it's 3 hours past your bedtime.
