Jonathon has a bag full of 14 balls to sell. he sells the baseballs for $2 dollars and the volleyballs for $5 and earns a total of $43. if the baseballs are represented by x and the volleyballs are represented by y, which of the following systems of equations can be used to calculate the number of baseballs and volleyballs sold? x + y = 14, 2x + 5y = 43 x + y = 43, 2x + 5y = 14 x − x + y = 14, 2x + 5y = 43 x + y = 43, 5x + 2y = 14
