An equation says two things are equal. It will have an equals sign = like this: That equations says: what is on the left (x − 2) equals what is...
Ah, but new experts will rise up and embrace the new, friendly Stack Overflow that they have always wanted. And maybe rediscover the same things the bitter, hateful old guard found.
It is NOT 'bad' to use the new keyword. But if you forget it, you will be calling the object constructor as a regular function. If your constructor doesn't check its execution context then it won't notice that 'this' points to different object (ordinarily the global object) instead of the new instance. Therefore your constructor will be adding properties and methods to the global object ...
You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15. Learn all about equations in math in this article.
A system of equations is a set of simultaneous equations, usually in several unknowns for which the common solutions are sought. Thus, a solution to the system is a set of values for each of the unknowns, which together form a solution to each equation in the system.
This article talks about different equations along with systems of equations, both linear and non-linear, providing techniques for effective solutions, along with methods to solve different type of equations like linear, quadratic, polynomial, exponential, or trigonometric.
