Jennie has 177 more songs downloaded on her mp3 player than Diamond. Together, they have 895 songs downloaded. What system of equations could be used to determine how many songs each girl has downloaded?

• j + d = 895; j = d + 177

• j + d = 895; j = d - 177

• j - d = 895; j = d + 177

• j + d = 718; j = d + 177
