x=2 and y=-1

plug in 3-2x for y for the equation 2x-6

ok. i am going to see if i can understand it so i can work on my next one

so, just tell me how i sovled it?

so you get the general concept

i am confused

ok, what is confusing now?

i guess the way it is written

ok, you have two equations and two variables

toussainr might be able to explain it differently...

ok, well then: the goal is find the values for each variable that satisfy both equations

My browser just froze, sorry

dpflan, please go ahead!!!

okay, I'm going to give it try, hoping I'm helpful

you have to equations. we are going to proceed in steps to make things easier!!!

So we have: 2x-2y = 6

AND

-2x-y = -3

Let's move on with step two

2. From equation "-2x-y = -3"
Let's derive a value for 'y'

We have -y = -3+2x
OR
y = 3-2x (we multiply by -1 the LHS and the RHS)

This value: "y = 3-2x" we are going to replace it in the first equation : 2x-2y = 6

We have now:

2x - 2 (3-2x) = 6

Let's multiply,. we have:
2x - 6 + 4x = 6

Let's perform the required addition: 6x-6 = 6

let's divide by 6 the RHS and the LHS, we have now : "x - 1 = 1"

Form here we can easily find the value of x :" x = 2"

THAT"S THE BEST I CAN DO!

thank you. I understand it more now. :)
