GCSE Maths Paper Just Gone?

Hello,

Recently I just took the Maths Linear GCSE Paper from Edexcel. There was a very odd question in it which went like this:

8 - ? 18 all divided by ? 2 = a +b? 2

Find a and b.

It went something like that. Anyway, surely that can't be solved because there's no other equation to go with it and if try solving for a or b individually then it just cancels out?

Please help! I am just wondering because of all the recent paper blunders that've happened.

Sorry, it's all divided by root 2. But I know how to do it now anyway, thanks

oops didn't see that bit, sorry

Yeah, my bad. I thought the root symbols would show but they didn't unfortunately. Apparently to do it you rationalize the denominator and stuff - but what I thought was HOW BADLY the question was shown, like the find a and b bit looked like another part of the equation, but it meant put it in the form of a + b to find a + b :/
