Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
Two tailors, Wendy and Haley, sit down to do some embroidery. Wendy can embroider 2 shirts per hour, and Haley can get through 6 shirts per hour. In addition, the tailors had previously finished some shirts. Wendy has already completed 20 shirts, and Haley has completed 4 shirts. Wendy and Haley decide to take a break when they have finished the same total number of shirts. How many shirts, in total, will each tailor have finished? How long will that take?
Each tailor will have finished a total of shirts ##28## in ##4## hours.
