Math homework, but an English lesson involved: Proper spelling is "equation."
Offhand I see possibly that we need to set up to solve 5690/6600= X/100 and cross-multiply, then solve for X
Do again for 950/6600=Y/100 and cross multiply. Solve for Y.
At least we get to put something together that replaces the original equation with X%+Y%=100%
Now, I am leading up to Y% is the percentage change, but I need to bone-up on that point myself. Perhaps I have triggered the thought juices.
