What does equivalent expression mean in math?

It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.


Ranger wants to verify that the expression8x โ€“ 20 is the correct simplified expression for 4(2x โ€“ 5). Explain how to verify the simplified expression?

Sample Answer: To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove equivalence.

What do expressions which use numbers or other symbols and an equal sign mean?

In mathematics, such expressions indicate that the value of the expression to the left of the equal sign has the same value as the expression to the right of the equal sign. In some cases, it can also be interpreted to mean that the expression on one side of the equal sign can be used in place of the expression on the other side of the equal sign (say in manipulating algebraic expressions). In computer languages, the equal sign is sometimes also used to indicate that the value of the expression to the right of the equal sign is to be transferred to the location indicated by the expression to the left of the equal sign. The expression to the left of the equal sign is usually a single variable that represents a memory location.


How do you know if the original expression is equivalent to the simplified expression?

you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.


Do expressions have the same value?

No, expressions cannot have the same value in algebra. They may be assigned to different values and on solving we can get different answers in each case.


When two expressions have the same value they are?

What are expressions that have the same value called?

They are identities.


Expressions that have the same value?

If both equations can be simplified to the same value, they are equal.


Will the value of the expression 20- x increase decrease or stay the same as x Explain?

If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.


What are expressions that have the same value no matter what x represents called?

algebraic expressions


Expressions that have the same value are called?

They are equivalent fractions.


To solve a system of equations you cannot replace a variable with an equal value or expression?

You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.

Why the expressions 7a and 9a are not equivalent even through they have the same value when a equals 0?

Because when a has any other value they do not have the same value.


What is the definition of two expressions that are equal or have the same value?

It is an equation


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


What does x mean in the expression -x6?

The same as in many other expressions. It is a variable, that is, it can be replaced by any number.


Do you solve an expression the same way you solve an equation?

If we are talking about the algebraic expressions, then an expression can be simplified or be evaluated for specific values of its variables, while an equation need to be solved, in other words to find the values of the variables that make the equation a true statement. If we are solving an equation, then we can work in the same way that we can simplify an expression (since an equation is a statement that states that two expressions are equal), or factoring an expression.
