I need help on this. I tried simplifying it, putting some numbers on it but there has to be a simple way to figure this one out.
Thanks in advance.
a, b and c are whole numbers.
$$a > b > c$$ $$ (a + 2b)/c = b $$ what is the lowest number that a can get?
I simplified into something like this but can't go any further
$$ c - (a/b) = 2 $$
And here are the choices: 8, 9, 10, 11, 12
