I keep trying to find the solutions for V by elimination but still can't find the answer. Any help would be much appreciated:
Each week the junior civil servant in Downing Street wheels a suitcase to the local supermarket to buy alcohol. He always spends the same amount of money.
In week 1 he buys 10 bottles of gin, 5 bottles of vodka and 9 bottles of wine.
In week 2 he buys 4 bottles of gin, 10 bottles of vodka and 12 bottles of wine.
In week 3 he buys 2 bottles of gin and 27 bottles of wine.
In week 4 the Cabinet Secretary decrees that only vodka can be purchased. How many bottles of vodka can he buy?
I've written this as:
10G + 5V + 9W = A
4G + 10V + 12V = A
2G + 27W = A
