System of two ordinary differential equation of different order

Hello everyone!

You typed y'.1 but should have typed y.1'

The latter looks ugly because the prime symbol is in the subscript, but its the correct syntax.

So either avoid indexed function names like Fred did or use the derivation operator d/dx
