They are useful in situation with many variables and can create useful digital images and can represent how a system or process works or.... all of the above....
Variables may be used for a number of different purposes. They may be used to generalise mathematical statements or to model a system of equations to solve.
It is algebra.

The type of Mathletics that uses letters instead of numbers is called algebra. Algebra is a branch of mathematics that uses symbols and letters to represent numbers and describe mathematical relationships and operations. It allows for solving equations and expressing patterns and equations in a general form.

Mathematical Model.
That refers to a system to represent numbers. For example, the decimal system we use in most of the world.
It is algebra.
Binary numbers have the virtue of being simple enough that they can be represented by a purely physical system, in which a magnetic north pole can represent (let us say) a 1, and a magnetic south pole can represent a 0, or a current being on can represent a 1 and the same current being off can represent a 0. In other words, the physical world contains analogs of binary systems. If you wanted to use decimal numbers you would have to find a physical system that has ten variables, which are relatively easy to measure and to create as needed, and that is not going to be easy.

A computer or computational device in which the problem variables are represented as continuous, varying physical quantities. An analog computer implements a model of the system being studied. The physical form of the analog may be functionally similar to that of the system, but more often the analogy is based solely upon the mathematical equivalence of the interdependence of the computer variables and the variables in the physical system.

Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.
In many mathematical applications letters represent quantities that are being solved for and that are not initially known. There are also applications in computer science where calculations have to be made using math in base other than ten. For example hexadecimal numbers are sometimes used to locate a spot in a system dump in order to troubleshoot a problem. In hex arithmetic, letters A through F could represent 10 through 15, the number 10 equaling 16.
