Ok, but can you give me an example so i can try?

here's an easy one: 2x + y = 3 x + y = 1

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
2x + y = 3 + x + y = 1 Is this the right first step?

you can do 3 different things to solve a linear system: 1. graph the equations, and find where they intersect. 2. substitution 3. elimination.

Im gonna do elimination then substitution

I cant do elimination on this one

2x + y = 3 + x + y = 12y 3x=42y

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
That cant be right

you can; in fact elimination would be the easy way out of this one

Can i divide the equations?
 2 years ago

agdgdgdgwngo Group TitleBest ResponseYou've already chosen the best response.3
if you subtract equation 2 from equation 1: you get x = 2 x + y = 1 next step is to subtract the new equation 1 from equation 2

agdgdgdgwngo Group TitleBest ResponseYou've already chosen the best response.3
you can't really divide the equations
 2 years ago

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
Ok, i see why now

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
Give me another one so i can try, i think i see the pattern

2x + y = 5 x + y = 3
 2 years ago

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
2x + y = 5  x + y = 3 = x=2? The y's cancel out right?
 2 years ago

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
Now i can substitute to get y
 2 years ago

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
2 + y = 3 y=1
 2 years ago

Inopeki Group TitleBest ResponseYou've already chosen the best response.2
I can cross check this with the other equation

4 + 1 = 5 2 + 1 = 3
