4r + 6d = 152
4r + 3d = 92
6d + 4r = 152
3d + 4r = 92
6d + 4r - (3d + 4r) = 152 - 92
6d + 4r - 3d - 4r = 152 - 92
6d - 3d = 152 - 92
d = 20
3 * 20 + 4r = 92
r = 8
4r + 3d = 92
6d + 4r = 152
3d + 4r = 92
6d + 4r - (3d + 4r) = 152 - 92
6d + 4r - 3d - 4r = 152 - 92
6d - 3d = 152 - 92
d = 20
3 * 20 + 4r = 92
r = 8
