An algebraic equation.
An open sentence.
An equation that contains at least one variable is (2x + 5 = 15). In this equation, (x) is the variable, and the equation states that when you multiply (x) by 2 and add 5, the result equals 15. Solving for (x) will allow you to find its value.
A = b.
An equation that contains a radical with a variable in the radicand is called a radical equation. These equations typically involve square roots, cube roots, or higher roots, and the variable is located inside the radical symbol. Solving radical equations often requires isolating the radical and then raising both sides of the equation to an appropriate power to eliminate the radical.

An open sentence.
It is an equation. It could be an algebraic equation, or a trigonometric equation, a differential equation or whatever, but it is still an equation.
Literal Equation
A = b.
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
