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 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.
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...

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).
You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.
It is one linear equation in two unknown variables.
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.
