Please hurry and answer I got 40 minutes left Payton bought packages of black T-shirts and packages of white T-shirts. Each package of black T-shirts contains 3 shirts. Each package of white T-shirts contains 4 shirts. Payton bought b packages of black T-shirts and 5 packages of white T-shirts for a total of 38 T-shirts.
Which equation could Payton solve to determine the number of packages of black T-shirts, b, he bought?
