What is the process of solving systems of equations when you add the two equations together in hopes of eliminating a variable?

You need to make the terms on each side as much alike as possible in the two equations for easy thought process.
For example, Let us look at the following two equations.
a * b = c * d --- (1)
x * d = k * a --- (2)
Rearrange (2) so that 'd' is on the right side of the equation and 'a' on the left.
a * k = x * d --- (3)
Divide (1) by (3):
b / k = c / x --- (4)
I have eliminated two variables from (1) and (2) to form equation (4).

Is an independent variable defined to be a variable that is to be predicted or estimated?
neither, an independent variable is a variable not being changed in the process of a science experiment. A variable in math cannot be described, only purpose of a variable is to take place of a number that you are trying to figure out in some equations. Others are equations with no solution.
How do you use different techniques to solve linear equations?
There are several techniques to solve linear equations. One common technique is the elimination method, where you eliminate one variable by adding or subtracting equations. Another technique is substitution, where you solve one equation for a variable and substitute it into the other equation. You can also use matrices and row operations to solve linear equations.

How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
Why are parametric eqautions bad?
In mathematics, parametric equations of a curve express the coordinates of the points of the curve as functions of a variable, called a parameter.[1][2] For example,are parametric equations for the unit circle, where t is the parameter. Together, these equations are called a parametric representation of the curve.A common example occurs in kinematics, where the trajectory of a point is usually represented by a parametric equation with time as the parameter.The notion of parametric equation has been generalized to surfaces, manifolds and algebraic varieties of higher dimension, with the number of parameters being equal to the dimension of the manifold or variety, and the number of equations being equal to the dimension of the space in which the manifold or variety is considered (for curves the dimension is one and one parameter is used, for surfaces dimension two and two parameters, etc.).The parameter typically is designated t because often the parametric equations represent a physical process in time. However, the parameter may represent some other physical quantity such as a geometric variable, or may merely be selected arbitrarily for convenience. Moreover, more than one set of parametric equations may specify the same curve.

How do you solve systems by elimination?
Select one equation from a system of linear equations. Select a second equation. Cross-multiply the equations by the coefficient of one of the variables and subtract one equation from the other. The resulting equation will have one fewer variable. Select another "second" equation and repeat the process for the same variable until you have gone through all the remaining equations. At the end of the process you will have one fewer equation in one fewer variable. That variable will have been eliminated from the system of equations. Repeat the whole process again with another variable, and then another until you are left with one equation in one variable. That, then, is the value of that variable. Substitute this value in one of the equations from the previous stage to find the value of a last variable to be eliminated. Work backwards to the first variable. Done! Unless: when you are down to one equation it is in more than one variable. In this case your system of equations does not have a unique solution. If there are n variables in your last equation then n-1 are free to take any value. These do not have to be from those in the last equation. or when you are down to one variable you have more than one equation. If the equations are equivalent (eg 2x = 5 and -4x = -10), you are OK. Otherwise your system of equations has no solution.

Where can you get a cheat engine for Linux?
scanmem scanmem is an interactive debugging utility that can be used to isolate the address of a variable in an executing process by successively scanning the process’ address space looking for matching values. By informing scanmem how the value of the variable changes over time, it can determine the actual location (or locations) of the variable by successively eliminating non-matches. apt-get install scanmem

Why would you want to export a variable in Unix?
You export a variable in one process so that a child process can have the value as well. If you don't export the variable then the child process cannot see it.
A variable that is changed during the process of experimentation is a?
The variable that is purposely changed is the independent variable. The variable that is affected by this change is the dependent variable.
