## sussycake 3 years ago a=b+c-2 a=c-d+9 a=b-d+11 based on the system of equations above, what is the value of a? (a) 2 (b) 9 (C) 10 (d) 11 (e) 20

1. sussycake

cheating for what? I don't know how to do this question so I'm posting. And you spelled "site" wrong.

2. eyust707

Here we have 3 equations and 4 unknowns. I believe this problem is indeterminate.

3. sussycake

i never said I want a straight answer. Do you have something against me? Why are you picking on me?

4. eyust707

Are you sure you typed it in correctly?

5. sussycake

Yep I did. this problem is from a sat practice book.

6. sussycake

that's the whole problem. What happens if the person comes up with a different answer other than the choices?

7. eyust707

The best I can do is give you a in terms of either b, c or d.

8. sussycake

I tried that but it doesn't work out for some reason.

9. eyust707

@lgbasallote any ideas?

10. lgbasallote

@trenvilla 's good....

11. lgbasallote

anyway...what did you try @eyust707 ?

12. sussycake

@ tenvilla I wasn't even talking to you

13. nincompoop

@trenvilla does not like Asians :P

14. sussycake

agree

15. lgbasallote

i think you failed to notice there are only 3 unknowns here since they're all equal to a

16. satellite73

jeez people are so touchy these days @sussycake there are more variables than equations here, so either there is a typo, one equation is missing, or the problem is posed incorrectly you can solve for one variable in terms of others, but you cannot assign a number to the variables

17. satellite73

when did people here get so uptight about the questions. take a pill

calm the math down, let's just help each other out, bros.

20. JackSmiley

Ok, I got a=0, but that's obviously not right.
