The System Of Elimination Calculator is a professional, user-friendly tool designed to solve simultaneous linear equations using the elimination method. This method is widely used in algebra to find the values of unknown variables by eliminating one variable at a time.

Whether you’re a student, teacher, or professional, this calculator simplifies complex calculations, saves time, and ensures accurate results, making it ideal for academic, scientific, and engineering applications.


How the System Of Elimination Calculator Works

The elimination method involves the following steps:

  1. Align the Equations – Ensure both equations are in standard form:

a1x+b1y=c1a_1x + b_1y = c_1a1​x+b1​y=c1​ a2x+b2y=c2a_2x + b_2y = c_2a2​x+b2​y=c2​

  1. Eliminate One Variable – Multiply or subtract the equations so that one variable cancels out.
  2. Solve for Remaining Variable – Once one variable is eliminated, solve the resulting equation for the remaining variable.
  3. Substitute Back – Substitute the solved value into one of the original equations to find the other variable.

The calculator automates these steps, instantly providing the solution for all variables.


Required Inputs

  1. Equation 1 Coefficientsa1a_1a1​, b1b_1b1​, and constant c1c_1c1​.
  2. Equation 2 Coefficientsa2a_2a2​, b2b_2b2​, and constant c2c_2c2​.

Optional Inputs:

  • Decimal Precision – Adjust the number of decimal places for solutions.
  • Multiple Variables – Some calculators allow 3-variable systems.

Expected Outputs

Once the inputs are entered, the System Of Elimination Calculator provides:

  • Values of Variables – Solution for xxx and yyy.
  • Step-by-Step Elimination – Shows how one variable was eliminated.
  • Verification – Confirms solutions by substituting back into original equations.
  • Consistency Check – Indicates if the system has no solution or infinite solutions.

This ensures users can not only get the answers but also understand the solution process.


Practical Example

Consider the system:2x+3y=162x + 3y = 162x+3y=16 4xy=104x – y = 104x−y=10

Step 1: Eliminate y

Multiply the second equation by 3:12x3y=3012x – 3y = 3012x−3y=30

Add the first equation:2x+3y+12x3y=16+30    14x=462x + 3y + 12x – 3y = 16 + 30 \implies 14x = 462x+3y+12x−3y=16+30⟹14x=46

Step 2: Solve for xx=4614=3.2857x = \frac{46}{14} = 3.2857x=1446​=3.2857

Step 3: Solve for y

Substitute xxx into the first equation:2(3.2857)+3y=16    6.5714+3y=16    3y=9.4286    y=3.14292(3.2857) + 3y = 16 \implies 6.5714 + 3y = 16 \implies 3y = 9.4286 \implies y = 3.14292(3.2857)+3y=16⟹6.5714+3y=16⟹3y=9.4286⟹y=3.1429

The solution is x=3.29x = 3.29x=3.29, y=3.14y = 3.14y=3.14.
