Word problem:

Gustav wants to find the exact mass of one millilitre of a particular oil. He wants as exact an answer as he can get, so he will measure more than one millilitre and then divide to find the mass, to minimize measurement error. He forgot to measure the mass of the container alone, but he knows how to solve a system, so he doesn't bother to do so. His measurements are as follows:
mass of the container and 50ml of the oil: 126.5g
mass of the same container and 100ml of oil: 165.5g

Where are you struggling? Did you write clear and concise definitions? That is a great place to start ALWAYS! You never have to have nowhere to start.

I'll do one:

C = Mass of Container Alone

Your turn.
