What is a math statement where two expressions have the same value?
They are called: Identical equations or IdentitiesSee: http://www.tutorvista.com/search/value-algebraic-expressions-33 - -7 = ss = -26
How do you classify algebraic expressions?
Algebraic expressions are terms that do not include an equality sign
How do you know if you will subtract or add in simplifying algebraic expressions?
Only like terms can be subtracted or added in algebraic expressions.
What is algebraic strategy for solving a system of equations when two expressions are the same?
An expression is the algebraic representation of a number - an expression has a numeric value.An equation is an algebraic statement claiming that two expressions have the same numeric value. The equation has a Boolean value (true or false).If two equations can be expressed in an identical manner (the same expression on both sides) - then these equations are the same equation.In order for a system of equations to have a solution, the number of different equations in the system must be equal to the number of variables in the system. If there are more distinct equations than there are variables, than the system has no solution. If there are less, then the system may have no solution, or infinitely many solutions.In the case described there is most likely an infinite number of solutions
Do algebraic expressions have to have a variable?
Yes. That is the definition of an algebraic expression.
Do algebraic expressions have equals signs?
no algebraic expressions do not have equal signs but equations do.
How are algebraic expressions and equations alike?
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.
When two expressions are equal in value?
They are callled: Identical equations or Identities See: http://www.tutorvista.com/search/value-algebraic-expressions
How an algebric expression with quadratic denominator is solved?
Algebraic expressions can't be solved because they are not equations but they can be simplified.

Why are algebraic expressions called variables?
Algebraic expressions may contain variables but they are not normally called variables. In fact, if they are related to identities, they need not be variable. For example, (4x2 + 8xy + 4y2)/(x + y)2 is an algebraic expression, but it is not a variable: it equals 4.
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
