There is a common factor on the coefficients of both variables that you can pull out to make the equation more simple to read.
4c - 2y
Notice how both 4 and 2 have a common factor of 2. So, we can pull it out by dividing both terms by 2.
Then we get
2(2c - 1y)
As an answer.
You can check to make sure this is right by multiplying the 2 back in.
