Question

Help find the x and y intercepts

3x + 5y = 0
5x + 3y = 16

Answer 1

x y intercepts? or x and y that they have in common?

Answer 2

What each have in common

Answer 3

does it matter how you solve it?

Answer 4

It is a system

Answer 5

solved by addition

Answer 6

3x + 5y = 0 [-5]
5x + 3y = 16 [3]


-15x -25y = 0
15x + 9y = 48
----------------
-16y = 48

y = -3

Answer 7

i think addition is the same thing as elimination....right?

Answer 8

What I did was this

(-3)3x + 5y = 0
(5)5x + 3y = 16

-9x - 15x = 0
25x + 15x = 80

16/16 \[\times\] 80/16

I got x = 5

Answer 9

3x + 5y = 0 [-3]
5x + 3y = 16 [5]


-9x -15y = 0
25x +15y = 80
--------------
16x = 80

x = 5

Answer 10

Can I find Y by using

3x + 5y = 0

?

Answer 11

once you find a solid value for a variable; you can just use it in an equation to find the other...

Answer 12

I got +3 when I used 3x + 5y = 0

Answer 13

no you dint lol

Answer 14

3x + 5y = 0

3(5) + 5y = 0

15 +5y = 0

5y = -15

y = -15/5

y = -3

Answer 15

Whoops! I forgot to add the - sign!

Thanks :D
