Answer 6

I got 8 lmao. am I right?

Answer 7

for real?!?!

Answer 8

yeah, that's what I got.

Answer 9

but what do I do now?

Answer 10

6?

Answer 11

oh, I thought you meant substitute 8 for 12! lol. that's still not the answer I'm looking for though.

Answer 12

so what now?

Answer 13

no! haha okay, no biggie.

Answer 14

1- multiply the second line by -1 so the sign will change...the system will become

x + 2y > 4
-x + y > 6

now multiply your second equation by 2 to get the y canceled out

x + 2y > 4
-2x + 2y >-6

can you solve for y now?

Answer 15

for x *

Answer 16

I get 1.5 am I right?

Answer 17

By Subtracting ,You will get :
3x > 10
x > ?

Answer 18

not sure! I'm confused!

Answer 19

================
Now substitute with 10/3 instead of x in
-2x + 2y >-6
Can you solve now for y ?

Answer 20

solve for Y or X?

Answer 21

I don't know how to do it with fractions!

Answer 22

For Y .....
-2(10/3) +2y >-6
-20/3 + 2y > -6
2y > -6 +20/3
2y > -38/3
y > -19 /3

Answer 23

Note :::
y > -19/3 = y > -6.3333..
x >10 >3 = x > 3.33333
Can you find a suitable order pair ?

Answer 24

when it comes to fractions, I have no Idea what I'm doing!

Answer 25

so.. what now?

Answer 26

it's C/

Answer 27

Find the order pair which suit them

Answer 28

I can't work with fraction lol/

Answer 29

You are left with 2 choices
C,B

Answer 30

c! @Eyad

Answer 31

yes right

Answer 32

thank you <3
