anonymous one year ago 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

arh...

3. anonymous

no biggie clear the fraction by multiplying EVERYTHING by 2

4. anonymous

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

5. anonymous

@satellite73

6. anonymous

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

7. anonymous

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

8. anonymous

Oh. okay let me try to solve it :)

11. anonymous

Right?

12. anonymous

yesh...

13. anonymous

wait im completely confused

14. anonymous

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

15. anonymous

right

16. anonymous

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

17. anonymous

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

18. anonymous

distribute on the right hand side

19. anonymous

2y=-1x-3

20. anonymous

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

21. anonymous

ohh so 2y=-1x-6

22. anonymous

correct?

23. anonymous

yes

24. anonymous

now add $$x$$ to both sides and you are done

25. anonymous

1x+2y=6

26. anonymous

yeah but drop the $$1$$ or your teacher will think you are daft

27. anonymous

so just x+2y=6

28. anonymous

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

29. anonymous

x-2y=6???

30. anonymous

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

31. anonymous

$x+2y=-6$ in other words

32. anonymous

Oh, well thanks.

33. anonymous

yw

34. anonymous

Im no math genius as you can tell

35. anonymous

lol that is fine, that is why you are doing homework, to learn it !

36. anonymous

I suppose lol. Thanks for making me feel better

37. anonymous

yw ( you will "get it" as they say)
