For example, these three equations are equivalent to each other:
- + 2 = 5
- + 1 = 5
- + 0 = 5
3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6x2 + 12y + 6.
How do you identify equivalent expressions?
Equivalent Expressions Equivalent Expressions are expressions that have the same value. They may look different but will have the same result if calculated. For example, and are equivalent expressions. See why below: The two expressions have the same answer, 27. Therefore, we can say that they are equivalent expressions.
How to write equivalent expressions?
the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for. 6.EE.A.2 Write, read, and evaluate expressions in which letters stand for numbers.
How do you find the equivalent expression?
equivalent expressionshave the same value but are presented in a differentformat using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the”equal” rather than 2 as shown here.
Which expressions are equivalent to?
Two mathematical expressions are equivalent if and only if they result in the same value for all matching values of the variables. Therefore, we can determine if two expressions are equivalent by plugging in many different matching values of the variables to make sure we get the same value out of each expression in every instance.
What are equivalent expressions?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
How do you write an expression equivalent?
You can write equivalent expressions by combining like terms. Like terms are terms that have the same variables raised to the same powers. For example, the list shows some pairs of like terms. the new coefficient is 9.

What are equivalent expressions?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value (s) for the variable (s).
When two expressions are equivalent, what is the meaning of the expression?
If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
How do we rearrange formulas?
Formulas are equations that contain or more variables; they describe relationships and help us solve problems in geometry, physics , etc.
How to make an equation true for all values of a variable?
For the equation to be true for all values of the variable, the two expressions on each side of the equation must be equivalent. For example, if for all values of , then: must equal . must equal . Distribute any coefficients on each side of the equation.
How to distribute coefficients?
Distribute any coefficients: Combine any like terms on each side of the equation: -terms with -terms and constants with constants. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What happens if all the terms in two expressions are identical?
If all of the terms in the two expressions are identical, then the two expressions are equivalent.
How to isolate a variable?
To isolate a specific variable, perform the same operations on both sides of the equation until the variable is isolated. The new equation is equivalent to the original equation.
How does Sal find equivalent expressions?
Sal finds equivalent expressions by combining like terms and using the distributive property.
Why do brackets and parentheses have to include the other one?
Brackets [] and Parentheses () both have to include the other one because you could see both. It also reminds us that division and multiplication are on the same level, so generally done left to right. Also, addition and subtraction are on the same level left to right.
