A. Designing and building an artificial heart for the human circulatory system

Explanation:

Whenever the term design and build comes into play, it's most times relating to engineering, Engineers takes out much time to work on each product from their design to their building, the application of Engineering importance cuts across all fields of life to making life easier for humanity in its innovation. The building and building an artificial heart for the human circulatory system is an engineering work perspective.

answer; ///i believe that the correct answer is (d); ///

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.
