Equations are made from expressions.
by getting the variable by it's self
An equation has the 'equals' sign ( = ) in it. An expression hasn't.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
a rational function.
expressions don't have an equal sign and equations do
similarities and differences between ordinary fractions and rational expressions.
Yes. An equation has an "=" sign.
Equations are made from expressions.
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
They can but don't have to.
In the same way that you would solve equations because equivalent expressions are in effect equations

no algebraic expressions do not have equal signs but equations do.
