The difference of rick's height and 16 is 57. the variable r equals rick's height

16 + r = 57 .
so ricks height is 48

First, the difference of Rick's height and 16 can be represented as r-16 because r represents Rick's height and difference means subtraction. When we set this equal to 57. we get r-16=57.

I hope this helps.
