An equation with two or more variables is called a polynomial. It can also be a literal equation.
It is a linear equation in two variables (x and y). Since there are two variables and only one equation, there can be no solution for x or y - other than in terms of one another (which just results in rewriting the one equation).
It could be a linear equation in two variables. A single linear equation in two variables cannot be solved.
It is a linear equation in two variables
It is called a polynomial.
An equation with two variables . . . seriously!An equation with one variable can be can be solved, but when there are two variables, you need two equations. This is called a system of two equations in two variables.Three equations in three variables, etc.
If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.

An equation with two or more variables is called a polynomial. It can also be a literal equation.
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
-1
substitution
If an equation has two variables, we'll call them (x,y), the variables can be any value as long as both sides of the equation have the same result. If the equation was x = y, then the variables could be (1,1), (2,2), (3,3),etc...
combining like terms or subtracting from both sides of the equation.
