Let’s check out your problem:

ate $20$ slices of pie, and Yasmin ate $4$ more slices than Zippy did. Which of the following systems of equations represents this situation in terms of $y$, the number of slices of pie Yasmin ate, and $z$, the number of slices of pie Zippy ate?$\newline$Choose $1$ answer:$\newline$(A) $y+z=20$$\newline$$$y+4=z$$$\newline$(B) $y+z=20$$\newline$$$z+4=y$$$\newline$(C) $y+z=20$$\newline$$$y=4 z$$$\newline$(D) $y+z=20$$\newline$$$z=4 y$$
