How do you do elimination in algebra?

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 first step when solving with elimination?

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

What does elimination mean in math?

noun. the act of eliminating. the state of being eliminated. Mathematics. the process of solving a system of simultaneous equations by using various techniques to remove the variables successively.

How do you solve systems by elimination?

What is the first step in elimination method?

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 3 methods used to solve systems of equations?

There are three ways to solve systems of linear equations in two variables:

  • graphing.
  • substitution method.
  • elimination method.

How do you solve a system of equations with multiplication?

Solving Systems Using Multiplication

  1. Put both equations into standard form (Ax+By=C).
  2. Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.
  3. Add the two equations together.
  4. Solve for the variable.

Can you multiply both equations in elimination?

You can multiply terms in one or both equations by a constant to set up your elimination. Then you can add or subtract terms in one equation from the other and eliminate a variable.

How do you solve by using elimination?

Express the word problem as a system of equations.

  • Solve for one of the variables.
  • Substitute the solved variable into the other equation.
  • Solve for the unknown variable.
  • Substitute the value of the unknown variable into one of the original equations to solve for the other unknown variable.
  • Check your solution.
  • How do you solve each system by elimination?

    Multiply one equation or both the equations by a non-zero constant so you get at least one pair of like terms with the same or opposite coefficients.

  • Subtract or add the equations to eliminate a variable.
  • Solve for the other variable.
  • Substitute this value in one of the equations.
  • Solve for the eliminated variable.
  • How do you multiply without using multiplication?

  • How do you solve system of equations by elimination?

    Write both equations in standard form. If any coefficients are fractions,clear them.

  • Make the coefficients of one variable opposites. Decide which variable you will eliminate.
  • Add the equations resulting from Step 2 to eliminate one variable.
  • Solve for the remaining variable.
  • Substitute the solution from Step 4 into one of the original equations.
