Question

i will medal and fan anyone who can help me
What is the x-coordinate of the solution to the system of equations?

2x + 6y = 8
4x – 5y = 33

Answer 1

what you would do first is figure out what x is and then you will plug that into both equations

Answer 2

so i solve one equation to figure out what x is and then plug it into the other equation?

Answer 3

yes

Answer 4

ok let me try the first one

Answer 5

ok

Answer 6

for the first one i got x=−3y+4 i am really confused @kgod

Answer 7

one second

Answer 8

take your time

Answer 9

im gonna solve it and send it to you

Answer 10

now plug in -3y+4 for x in both of the equations

Answer 11

ok one sec

Answer 12

@kgod was i suppose to get a fraction

Answer 13

you can get a fraction that is fine

Answer 14

ok i got 2/3 for the first one

Answer 15

now plug it into the other equation

Answer 16

x=7 and y=-1

Answer 17

thanks Mrs.Allison how did you get that ?

Answer 18

@Mrs.Allison is correct

Answer 19

ill send you in a sec

Answer 20

ok

Answer 21

I became a fan of you both k

Answer 22

same.. thanks very much

Answer 23

no problem

Answer 24

in the first equation you isolate "2x", so it goes like this:
2x=8-6y
now you place that in the place of x in the other equation, note that the other equation is "4x" so you have to multiply this expression by 2

Answer 25

@MiggityMiggityMac I gave you the best response

Answer 26

then it goes like:
2(8-6y)-5y=33

Answer 27

thanks

Answer 28

solving this you get:
16-12y-15y=33
-17y=33-16
-17y=17
y=-1

Answer 29

and ok @Mrs.Allison

Answer 30

i think i need to review this stuff some more

Answer 31

why do you isolate 2x?

Answer 32

you need thes rest or you got it?

Answer 33

@Mrs.Allison woudnt you have to divide2x=8-6 to get x not 2x

Answer 34

do you do that for the second one too?

Answer 35

afk

Answer 36

probably

Answer 37

i could isolate y, its your choice, you just have to isolate one of the letters. Also, you coould isolate just x then it would be:
x= 8-6y/2

Answer 38

(all divided by 2)

Answer 39

and that would come out to be x = -3y +4

Answer 40

so, after you found out y=-1, you go back to that first equation and place the -1 in place of y and youll find x

Answer 41

yes @kgod

Answer 42

just making sure

Answer 43

thats ok

Answer 44

I was wondering if you could help me with a question

Answer 45

of course i can, im a teacher, im here to help you guys

Answer 46

ok thank you very much Mrs.Allison!!

Answer 47

The graph: A coordinate plane with a colored in, closed figure. Each segment must be labeled.


2.The inequalities: Show the work for finding the inequality that defines each segment.


3.A point: Choose a point within the boundaries of the shape, and show algebraically that the point satisfies all of the inequalities.

Answer 48

you are welcome, make sure to study that a little bit more and do all you homework so you can practice. @MiggityMiggityMac

Answer 49

there are only those information?
