Question

What is the solution of the following system?

Answer 1

use
elimination method to figure it out

Answer 2

i dont know how to do that

Answer 3

do yo know how to do that?

Answer 4

no >.<

Answer 5

sorry i was getting dinner

Answer 6

@iforgot help?

Answer 7

elimination

-1 [ax - by = 1 ]
ax + by = 1

-ax + by = -1
ax + by = 1
---------------
0ax + 2by = 0
solve for one term first

Answer 8

-2 [ax - by = 1 ] < multiply them
2 ax + by = 1 < with any number as long as
^ ^
|____ |________ one term a or b is elminiated = 0
so you can you solve the equation

Answer 9

so do i times them both by 4 and -4?

Answer 10

first of all
how do you solve an equation like this

2 = x + 2

Answer 11

uhhhh you minus 2 to both sides and x=0

Answer 12

correct you solve for x

it is in the form

x = number

Answer 13

okay

Answer 14

what would i have to multiply to eliminate one of the terms (the column)

Answer 15

this is distributed

-1 [ 2x - 2y = 2 ]
2x +2y = 1
----
0x
---
4 y = 1

solve for y
y = 1/4

substitute what you got
y = 1/4

2x + 2 (1/4) = 1

now you can solve

Answer 16

Is this supposed to be the answer to the problem ?

Answer 17

no it is an example

Answer 18

ok...just checking

Answer 19

I thought you wrote the problem down wrong...my bad...sorry iforgot

Answer 20

I hope he knows about no solutions and infinite solutions

Answer 21

because one of them will apply here
