elimination

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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"

argh you beat me.

lol

saifoo.khan · Answer

x = -3/11

y = 27/11

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

khan please redo the problem

anonymous · Answer

saifoo, you're wrong.   27/11-9/11=18/11 which is not 9

anonymous · Answer

$$y=2x+3$$
$$3x+2x+3=9$$
$$5x=6$$
$$x=\frac{6}{5}$$

anonymous · Answer

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

anonymous · Answer

lol jibble you crack me up

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

I'd probably be waiting for a while, huh?

anonymous · Answer

lol ya while you wait it will be learning its lesson
