Question

what is the solution to the system of equations 4x+y=2
x-y=3

Answer 1

Welcome to OpenStudy! We can solve this by elimination or substitution, it's up to you :)

Answer 2

yeah

Answer 3

Which one do you want to use?

Answer 4

4x+y=2

Answer 5

We need to solve both equations by substitution or elimination

Answer 6

substitution

Answer 7

Okay :) So we need to get x or by by itself in either equation, I think x-y = 3 will be easiest to work with, what do you think?

Answer 8

yes

Answer 9

Okay, so let's get x by itself since it's already positive :) do you know how to do that?

Answer 10

take it out ?

Answer 11

We need to move -y to the right side of the equation

Answer 12

Dont We Need To Put Those Together

Answer 13

Put what together?

Answer 14

4x+y=2
x-y=3

Answer 15

That is elimination

Answer 16

Which Would Be Easier

Answer 17

It really doesn't matter with this one, both ways will be about the same, but probably elimination if you know how to do it
