## How do you find equivalent expressions?

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

## What are 2 expressions are equal?

An equation is a mathematical statement that two expressions are equal. The solution of an equation is the value that when substituted for the variable makes the equation a true statement.

## Does 2x 2 equal?

Because 2x squared is equivalent to 2x raised to the second power, we can use this rule of exponents to evaluate 2x squared.

## What is an example of an equivalent expression?

Examples of Equivalent Expressions

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.

## Is 2x and 2y like terms?

Summary. Like terms are terms that have exactly the same variable and power in them—whether that’s x, x3, y, or even no variable! … But 2x and 2y would not be like terms because they have different variables, x and y.

## What is the equivalent to 7 12?

58
This means 712 is equivalent to 58. ¯¯¯¯33100 . When we have a fraction with a denominator of 100 , the numerator gives us the percent, since the word “percent” literally means per 100 . This means the fraction is 58.

## What algebraic expression means?

## How do you write expression?

To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.

## What is algebraic expression examples?

An algebraic expression is a mathematical phrase where variables and constants are combined using the operational (+, -, × & ÷) symbols. An algebraic symbol lacks the equal (=) sign. For example, 10x + 63 and 5x – 3 are examples of algebraic expressions. … For example, x is our variable in the expression: 10x + 63.

## How can we describe 3x 2 as an expression?

A coefficient is a number that is multiplied by a variable in a mathematical expression. … In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.

## What does an expression look like?

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

## How do you differentiate expression from equation?

You can define a numerical expression as a group of numbers and variables with no equal sign. An equation is a group of numbers and variables that does include an equal sign.
