How is writing an equation to represent a situation involving two variables similar to writing an equation to represent a situation involving only one variable?

An equation with only one variable has only one letter used in it, and that letter is usually an "x"
An equation having two variables will have two different letters representing them, usually the letters "x" and "y"
The first type could be the equation 5x^3 - 3x^2 + 6x - 50 = 0
The second type could be (x +y)^2 - 7x^3 + 12x = 58.8
1 equations with only 1 variable are usually much easier to solve than an equation with 2 variables, and you cannot solve the latter unless you have two separate equations containing the two variables.

What is the definition of literal equation?
Literal equation refers to an equation in which the variables represent known values. This type of equation allows the representation of things like distance, interest, time, and slope as variables in an equation.
What is literal equations?
A literal equation is an equation where variables represent known values. Literal equations allow us to represent things such as distance, time and interest as variables in the equation.. Using variables instead of words is a 'time saver'. For example d=rt. Meaning distance = rate and time
How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
What is the set of an equation in two variables in the set of all points in a coordinate plane that represent all the solutions of the equation?
To graph the set of all the solutions to an equation in two variables, means to draw a curve on a plane, such that each solution to the equation is a point on the curve, and each point on the curve is a solution to the equation. The simplest curve is a straight line.
An equation that contains two or more variables?
literal equation
What is an equation involving two or more variables?
An equation with two or more variables is called a polynomial. It can also be a literal equation.
An equation involving two or more variables?
algebraic
A situation in which variables lies?
an equation

What decisions do you need to make when you write an equation to represent a relatiship between variables?
You have to decide what the meaning of the equation will be.
What is an mathematical phrase involving constants variables and operation symbols?
It is an expression and if it contains an equality sign then it is an equation.
What decisions do you have to make when you write an equation to represent a relationship between variables?
an equal sign
How do you solve x equals t-yz?
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
What are the variables in this equation 3ab plus c over 2?
The variables of this equation are your letters: a, b, and c. Variables merely stand in an equation to represent values that we don't know. "Solving" an equation is the process by which we uncover those values. In this particular case, since there are three variables, we cannot discover their values unless we have two other equivalent equations (a system of equations).
Why is it important to use variables?
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.
What is the definition of equation in two variables?
It is an equation, involving mathematical terms, in which there are two elements, x and y, which are allowed to vary. For example 2x + sin(y) = 10xy
