## How do you solve an algebraic equation by elimination?

The Elimination Method

1. Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
2. Step 2: Subtract the second equation from the first.
3. Step 3: Solve this new equation for y.
4. Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

## What are the 4 steps for solving systems of equations by elimination?

Step 1: Put the equations in Standard Form. Step 2: Determine which variable to eliminate. Step 3: Add or subtract the equations. Step 4: Plug back in to find the other variable.

## What are the five steps for solving a system of equations by the method of elimination?

Step 1: Put the equations in Standard Form. Step 2: Determine which variable to eliminate. Step 3: Add or subtract the equations. Step 4: Substitute back in to find the other variable.

## How do you solve systems of equations by elimination?

HOW TO SOLVE A SYSTEM OF EQUATIONS BY ELIMINATION.

1. Write both equations in standard form.
2. Make the coefficients of one variable opposites.
3. Add the equations resulting from Step 2 to eliminate one variable.
4. Solve for the remaining variable.
5. Substitute the solution from Step 4 into one of the original equations.

## What is the method of elimination?

The elimination method is the process of removing the variable from the system of equations, whereas the substitution method is the process of replacing a variable with a value to find the solution for the system of equations.

## What are the steps to solving a system of equations?

1. Step 1 : First, solve one linear equation for y in terms of x .
2. Step 2 : Then substitute that expression for y in the other linear equation.
3. Step 3 : Solve this, and you have the x -coordinate of the intersection.
4. Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

## How do you solve by elimination with two variables?

Solve this system of equations by using elimination.

1. Arrange both equations in standard form, placing like terms one above the other.
2. Select a variable to eliminate, say y.
3. Add the new equations, eliminating y.
4. Solve for the remaining variable.
5. Substitute for x and solve for y.

## How can we solve systems of equations using elimination?

The elimination method for solving linear systems . Another way of solving a linear system is to use the elimination method . In the elimination method you either add or subtract the equations to get an equation in one variable.

## How do you calculate system of equations?

Solve by Multiplication Write one equation above the other. Multiply one or both equations until one of the variables of both terms have equal coefficients. Add or subtract the equations. Solve for the remaining term. Plug the term back into the equation to find the value of the first term. Check your answer.

## How would you solve this system of equations?

3 Methods for Solving Systems of Equations Substitution. Substitution is a method of solving systems of equations by removing all but one of the variables in one of the equations and then solving that equation. Elimination. Augmented Matrix. Determining the Solution. Applications.

## How do you solve system by substitution?

Substitution Method. One way to solve systems of equations is by substitution. In this method, solve an equation for one variable, then substitute that solution in the other equation, and solve. Use substitution as a method for solving a system of equations when the number of equations and variables is equal (if two variables,…
