# Which are equivalent equations select two correct answers

## What are the equivalent equations?

Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

## What is an example of an equivalent equation?

For example, if we take 3x + 12 = 7x – 2 and subtract 3x from both sides and add 2 to both sides, we get 14 = 4x. In doing this, we haven’t changed the solution set, so 3x + 12 = 7x – 2 and 14 = 4x are equivalent equations.

## How do you identify equivalent equations?

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 is an equivalent expression in math?

Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.

## What are equivalent functions?

Two functions are equal if they have the same domain and codomain and their values are the same for all elements of the domain.

## How do you equate two equations?

Suppose we have a pair of simultaneous equations, 2x − y = −2 and x + y = 5. We can solve these equations by taking the sum of the left hand sides and equating it to the sum of the right hand sides as follows: 2x − y + (x + y)=3x = 3. So, x = 1.

## How do you solve equivalents?

To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.

## What is an equivalent linear equation?

Two systems are equivalent if either both are inconsistent or each equation of each of them is a linear combination of the equations of the other one. It follows that two linear systems are equivalent if and only if they have the same solution set.

## What are equivalent linear equations?

Two systems are equivalent if either both are inconsistent or each equation of each of them is a linear combination of the equations of the other one. It follows that two linear systems are equivalent if and only if they have the same solution set.

## How do you solve equivalents?

To solve equivalent equations, follow these five steps:Step 1 – Use the distributive property, if necessary.Step 2 – Combine like terms on the same side of the equal sign, if needed.Step 3 – Collect the variable being solved for on the same side of the equation.More items…•
