Question

Suppose you have these two expressions:

1/2 = C -A
-1/2 = A - C

What is A =?, What is C =?

Answer 1

When I try to equate the above, I get 0 = 0....

Answer 2

lol fix it... say: suppose you have THIS expression: ... why?

note.
1/2=C-A
and
-1/2=A-C
is actually the same ... when we multiply both sides by -1 in the "second" equation
we get
1/2=C-A

Answer 3

Yes I understand that, but what would C, A be then, if the equations are exactly the same?

Answer 4

so baisically subsitute one valu for the other right?

Answer 5

you should Have at least 2 system of equations to find two different variabiles.

Answer 6

if you'd have
\[\LARGE \frac12 =C-A\]
and
\[\LARGE \frac34=4A-2C\]
maybe we could do something... but without having two diffenrent equations. You can't.

Answer 7

Both equations are exactly the same.

Answer 8

yeah I know. That's the problem :(

Answer 9

no solution
