True.
Several methods exist. For example: solve one equation for one variable, replace that variable in the other equation. (Two simultaneous equations will often have two variables each.)
-- 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.
There are several methods to do this; the basic idea is to reduce, for example, a system of three equations with three variables, to two equations with two variables. Then repeat, until you have only one equation with one variable. Assuming only two variables, for simplicity: One method is to solve one of the equations for one of the variables, then replace in the other equation. Another is to multiply one of the equations by some constant, the other equation by another constant, then adding the resulting equations together. The constants are chosen so that one of the variables disappear. Specifically for linear equations, there are various advanced methods based on matrixes and determinants.
an algebraic equation that describes a relationship between several variables is called a?

a function!
An equation that has several letters or variables is a polynomial
True.
I never heard about a "two-step equation". I believe it's the solution process which may have one or several steps.
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
In statistics, regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.
It very much depends on the equation. The procedure for solving an equation with just one variable is so very different from the procedure for finding solutions to non-linear equations in several variables.
'Manipulating variables' means to change some of the portions of a specific formula that are open to change, and hence variable. Take: ( x + y ) = 5 You may discretionally change the variables x and y to anything from minus infinity to five and the equation will still be solvable. To do so would be to manipulate those variables.
Yes it can. Most experiments will have several variables.
