Question

Okay now I have no clue how to solve this one.
Rewrite the equation in Ax+By=C form.
Use integers for A,B,C

Answer 1

arh...

Answer 2

no biggie
clear the fraction by multiplying EVERYTHING by 2

Answer 3

Right, So how exactly? Do you make 1/2 to just 2?

Answer 4

@satellite73

Answer 5

no dear \(2\times (-\frac{1}{2})=-1\)

Answer 6

but don't forget to multiply all by 2
all the way across
left hand side and right hand side,each term

Answer 7

Oh. okay let me try to solve it :)

Answer 8

kk

Answer 9

Right?

Answer 10

yesh...

Answer 11

wait im completely confused

Answer 12

lets go slow again
you want to get rid of the fraction right? so that the coefficients are "integers"

Answer 13

right

Answer 14

you got
\[y=-\frac{1}{2}x-3\]

Answer 15

to get rid of the two in the denominator, multiply both sides by \(2\)
\[2\times y=2\times (-\frac{1}{2}x-3)\]

Answer 16

distribute on the right hand side

Answer 17

2y=-1x-3

Answer 18

hmm looks like you forgot the distributive property
you also have to multiply \(-3\) by \(2\)

Answer 19

ohh so 2y=-1x-6

Answer 20

correct?

Answer 21

yes

Answer 22

now add \(x\) to both sides and you are done

Answer 23

1x+2y=6

Answer 24

yeah but drop the \(1\) or your teacher will think you are daft

Answer 25

so just x+2y=6

Answer 26

damn, dropped the minus sign again on the right didn't you?

Answer 27

x-2y=6???

Answer 28

a common mistake actually
now on the right, it was \(-6\) so it is still \(-6\)
