Explain how bone cells embedded in a solid ground substance obtain nutrients and eliminate wastes

Through blood vessels

Explanation:

Bones are made up of osseous connective tissue. These osseous connective tissues are made up of sparse cells within the extracellular network, or matrix . This matrix is made up of protein and minerals. The bone cell named Osteoblasts provides tensile strength to the bone by releasing proteins into the matrix. Collagen is the protein part of this bone matrix while the remaining part of bone matrix is made up of minerals  which provide hardness and compressive strength. Bone cells are living cells and they receive nourishment through the blood. The food delivery and waste removal is done by the blood vessels which pierce into the hard compact surface of the bone.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
