When viewing a specimen through a light microscope, scientists use special stains to distinguish the individual components of cells.

Explanation:

Microscope cell staining -

Microscope cell staining is a method that is used to for the better visualization of the cells and the parts of the cell , when are studied under microscope .

Stains are basically a type of biological tissues .

By the use of different type of stains , a nucleus of the cell or the cell wall of the cell are viewed easily , cells are sometimes stained in order to highlight metabolic process and can be used to find the difference between a dead or a live cell .

Some type of stains are specific for living cells , but some stains can work both for living as well as the non living cells .

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.
