What Is An Example Of An Equivalent Equations?

Two equations are said to be equivalent when they have the same solution set. For example,

x + 2 = 6 and 2x = 8

are equivalent equations, because when we solve each of them as follows, they have the same solution set. Subtract 2 from both sides. … Therefore, the two equations are equivalent.

What is an equivalent equation in math?

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 equivalent equation?

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 are equivalent equations Brainly?

Answer: Equivalent equations are

. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.

How do you solve an equivalent equation?

1. Step 1 – Use the distributive property, if necessary.
2. Step 2 – Combine like terms on the same side of the equal sign, if needed.
3. Step 3 – Collect the variable being solved for on the same side of the equation.

Are these 2 equations equal?

Two systems of equations are equivalent if they have the same solution(s)

. … Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.

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.

What is an equation that has an infinite number of solutions?

The

equation 2x + 3 = x + x + 3

is an example of an equation that has an infinite number of solutions.

What are the 4 steps to solving an equation?

We have 4 ways of solving one-step equations:

Adding, Substracting, multiplication and division

. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.

How do you solve an equation with two variables?

1. Step 1: Solve one of the equations for one variable.
2. Step 2: Substitute this in the other equation to get an equation in terms of a single variable.
3. Step 3: Solve it for the variable.
4. Step 4: Substitute it in any of the equations to get the value of another variable.

How do you tell if a system of equations has no solution or infinitely many?

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said

to be inconsistent

. The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

How do you know if an equation is true?

To make a true equation,

check your math to make sure that the values on each side of the equals sign are the same

. Ensure that the numerical values on both sides of the “=” sign are the same to make a true equation. For example, 9 = 9 is a true equation. 5 + 4 = 9 is a true equation.

How can you tell if two systems of linear equations are equivalent?

Two systems of linear equations are equivalent

if and only if they have the same set of solutions

. In other words, two systems are equivalent if and only if every solution of one of them is also a solution of the other.
