Mr. Elliot is extremely careful with his money. He recently invested part of his $150,000 life savings in gold bullion and the rest in a nuclear blast-proof bank. Mr. Elliot earned a 5% profit on his gold bullion and a 3% profit on the money in the bank. If he made a total of $5,500 from both investments, how much did he invest in gold bullion?

.03x + .05(150,000 - x) + 5,500
solving for both, but neither came out right.
