L = 3*(L - M)
2*(L + 2) = 2*(M - 2)

That's how I see it, use simultaneous equations to solve it.

Actually, now that I look at it again I don't think the first is correct.

But that's as much effort as I'm willing to give it.

:p

L=3(2M-L)
L+2 = 2(M-2)

so the reason i got it was: Laura is 3 times as old as Maria was when Laura was as old as Maria is now

so when laura was 18, maria was 6, thus 3 times older

thus making their present ages 18 = maria, and 30 laura

in 2 yrs. Laura will be twice as old as Maria was 2 yrs ago

in two years laura will be 32, and two years ago maria was 16, thus double

i basically did guess and check for a few ages

L=3(2M-L)

this comes from L= 3(M-(L-M))

to interpret the first condition, think of this way. subtract the difference between laura and maria from maria. multiply that by three, and you have laura's age.

L+2 = 2(M-2)

i hate it when i hit quote instead of edit

I agree totally and your post helps me think I'm not quite as stupid as reading the sentence makes me feel.

ANyway the ONLY way to satisfy the second part is if laura is 4 and marie is 5. And that doesn't mean anything with the first babbling sentence.

Oh right - 30 and 18, not 18, 30 ;) that works too, but I think that that and 4,5 are the only ones that do. That first sentence is still meaningless.

That's what I get for trying to do math while burning CD's, listening to music, & trying to get dinner ready.
