-- Pick a number out of a hat or a telephone book, or ask the person
standing next to you to give you a number.
-- Assign that number to one of the variables.
-- Solve the equation for the other variable.
-- This gives you one "ordered pair" solution of the equation.
-- Repeat, as many times as you want. You will never run out of solutions,
and you will never find all of them, as there are an infinite number of them.
you can find it by counting how many numbers they are in the equation
No, but eliminating variables is one of several ways to find the value of variables in a system of equations.
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

If the discriminant of the quadratic equation is equal or greater than zero it will have 2 solutions if it is less than zero then there are no solutions.
to find the unknown variables
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.
When you graph the quadratic equation, you have three possibilities... 1. The graph touches x-axis once. Then that quadratic equation only has one solution and you find it by finding the x-intercept. 2. The graph touches x-axis twice. Then that quadratic equation has two solutions and you also find it by finding the x-intercept 3. The graph doesn't touch the x-axis at all. Then that quadratic equation has no solutions. If you really want to find the solutions, you'll have to go to imaginary solutions, where the solutions include negative square roots.
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
Dimension is = the number of variables used in the equation
It is essentially a list of equations that have common unknown variables in all of them. For example, a+b-c=3 4a+b+c=1 a-2b-7c=-2 would be a system of equations. If there are the same number of equations and variables you can usually, but not always, find the solutions. Since there are 3 equations and 3 variables (a, b, and c) in this example one can usually find the value of those three variables.
To find the solutions of x in a quadratic equation.
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
the formula you are going to use to answer the equation
if you can, you could always search a online calculator and use that.
To find the roots (solutions) of a quadratic equation.
find equation of the line. write equation in slope intercept form. (5,5) parallel line (3,13) and (12,13)
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
It really depends on which equation you're looking at
On the x axis when y equals 0
I suggest you use the quadratic formula.
Variables are simply used as a connection to the real world, a variable may represent a number you have to find and you can use an equation to do so.
