Answer:

Greg's score plus 20 is equal to 64.

In equation form, this is 20 + g = 64

20 + G = 64
20 is the known constant and is a known variable and is a addend to the score while G is another addend but we just don’t know the value so when you put the equation together the 20 would stand for the known addend and the G would stand for the unknown addend which both equal to 64z
