Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks Wesley and his workout partner are lifting weights together, doing many sets of each exercise. On a certain exercise, Wesley is using a 13-pound bar, increasing the amount of weight he lifts by 5 pounds on each set. His partner, meanwhile, started out using a 16- pound bar and is upping the weight by adding 4 pounds on every set. Eventually, Wesley and his workout partner will be lifting the same amount, and will take turns using the same barbell. How many sets will they have completed? How much weight will they be lifting then? After completing sets, they will both be lifting pounds. Submit​
