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.
substitution
-1
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.
