Guys, I need you so badly...haha..It\'s about Intermediate Algebra!!!

This is about Solving systems of linear equations by graphing.Can u please explain me how to graph this 2 equations. ? : x+2y= -4 and 2x - y = 7 Please, explain it by details, step 1 step 2 etc..Coz I'm not really good in Math!....Thanks guys..I need the answer as soon as possible.. :) Guys, please take note of the word ''graph''...because that's what im askin to graph this two equations..thanks again..!

Okay ill try giving it a shot:)

1: x+2y= -4

(we substitute y with 1 (sense x = 1), and when a number and letter are close together without spaces (2y) that means that you times them.

x+2(1x)= -4 / = x+2+ -4

(remember we have to minus 2 (our new number) on both sides) x+2(-2)= -4 (-2)

Sense a - and - = +, our answer should be x= -6

2: 2x - y = 7 (x = 1

Sense their close together without spaces we times them. 2(x1) - y = 7

2 - y = 7, (minus 2 (senses its our new number) from both sides ) = - y = 5

( Recall that -1 x a = -a ) So now our y is negative = -y = 5

(y = -1) So we divide -1 both sides. Our answer is y = -5

Thanks so much.!..But...Why is it that x=1...?

I dunno just my math teacher said to treat X's like they were ones cause thats what they equal. You know x5 is the same as 1 x 5....
