Question

Hi guys, can you soulve this please?
My Assignment...

y-2x=3
3x+y=9

Substitution?

Answer 1

use eliminatiom

Answer 2

elimination

Answer 3

--um...im just a beginner...? i need the coordinates?

Answer 4

elimination y-y+-2x-3x=3-9
so -5x=-6
so x=6/5
then you can subts the x-value in either one of the equations to get y=27/5
hope i helped

Answer 5

you can subtract the entire equations from each other, leaving 5x=6 (or x=6/5) and then put it in for x so y-12/5=3 which makes y "5and2/5"

Answer 6

argh you beat me.

Answer 7

lol

Answer 8

x = -3/11

y = 27/11

Answer 9

--nice...i hope im like you....

i usd ny calc. :O

Answer 13

my*

Answer 14

\[y=2x+3\]
\[3x+2x+3=9\]

Answer 15

it lied. My calculator lies to me all the time. I have to send it to bed without dinner.

Answer 16

lol jibble you crack me up

Answer 17

\[3\times \frac{6}{5}+y=9\]
\[frac{18}{5}+y=9\]
\[y=9-\frac{18}{5}\]
\[y=\frac{27}{5}=5.4\]

Answer 18

you can just remove its battery and wait for it to come and apologise

Answer 19
