Answer 4

well why should I message you about helping ? I am ready to help already ..Post your questions/doubts I can surely guide you with good inputs

Answer 5

Okay! Thank you so much! to start off I am a lot behind in math because My school also has sucky percentages of their state test scores so I'm moving schools by the end of this year. and last year (8th grade) I failed the reading, writing, math, and science state tests! So I'm just trying to help myself to at least meet the requirements for this years!

Answer 6

I started getting behind in Systems of Equations and Inequalities.

Answer 7

Solving Systems by Graphing

Solve each system by graphing. (Is there another way, with an equation, instad of graphing?)

y= 2x
y= -2x +8

and then I didn't get the one with the fraction either:

y= 1/2x + 7
y= 3/2 + 3

Answer 8

By the way thank you so much! :) @AravindG

Answer 9

to solve :

y= 2x
y= -2x +8

you have different methods including graphing method

Answer 10

easiest method would be to add the two given equations



y= 2x
+ y= -2x +8
___________

2y=0+8
y=4

Answer 11

to get corresponding x value plug the y value in any of the equation above ..For simplicity I am taking first equation

y=2x
4=2x
x=2

Answer 12

did you understand that ?

Answer 13

No.... I don't understand how you got the 4?

Answer 14

I just added the 2 equations

Answer 15

Nevermind you adde3d the 2's

Answer 16

yeah...

Answer 17

Sorry! :/ my bad.

Answer 18

np ..I can understand .Everyone will face difficulty when you start with this topic believe me !

Answer 19

Its just take practice :)

Answer 20

haha yes. practice makes perfect. :) But wouldn't that be 4x? and you can't add a neg. to a pos, without having to subtract it.

Answer 21

ya I just added them

2x+(-2x)=2x-2x=0

Answer 22

Oh okay!

Answer 23

by the way khan's academy has good lectures on this topic

Answer 24

I've tried that over the summer but I would need a coach if I had any questions so it didnt really work for me because i had a lot of questions

Answer 25

well then I found this tutorial really simple and illustrative ...
