Let j denote the amount that Jim earned.

Let d denote the amount that Debbie earned.

Last month, Jim and Debbie earned $7,200

Mathematically, we can write it as


j+d=7200

Debbie earned $1,600 more than Jim earned.

Mathematically, we can write it as


d=j+1600

Therefore, the system of equations is


\begin{gathered} j+d=7200 \\ d=j+1600 \end{gathered}
