Answer 1

@mathmale

Answer 2

@No.name plz help me when u are able to madal awarded

Answer 3

Dude i am going to sleep , sorry wish to help you but it is like
2 in the midnight

Answer 4

ok ty anyways :)

Answer 5

(-8,-4)

Answer 6

hey tysm but can u plz explain :D:D

Answer 7

You can try substitution or elimination method, do you know either of these?

Answer 8

I know the elimination but not substitution

Answer 9

Okay so lets try eliminations. Times the top by 3 and the bottom by -2, then combine them.

Answer 10

try to make from equation one a value to Y with respect to X
and then plug it in equation two to get X value
then by applying the value of X in any of the 2 equations you can find Y value
and then you can find the (x,y) !! soo easy

Answer 11

did you get it ?

Answer 12

not really still trying to figure it out im really not good at this :/ iv been working on this since this morning and I cant think straight

Answer 13

actually no choice is right !!

Answer 14

but there has to be an answer

Answer 15

idk
but i`ll give you the strategy

Answer 16

but first be sure that you copied the choices correctly

Answer 17

Alright, so this one is easy, it's only 2 :)

Answer 18

We'll use substitution since it's basically set up for it haha. 2x= 5y+4 first thing, you want to isolate x, do that now for me please, and tell me what you get.

Answer 19

i know but every time i try to solve them i get solutions different from the ones given above !! try it your self @iambatman

Answer 20
