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:

$$a_1x + b_1y = c_1$$a1​x+b1​y=c1​ $$a_2x + b_2y = c_2$$a2​x+b2​y=c2​

2. Eliminate One Variable – Multiply or subtract the equations so that one variable cancels out.
3. Solve for Remaining Variable – Once one variable is eliminated, solve the resulting equation for the remaining variable.
4. 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 Coefficients – $a_1$a1​, $b_1$b1​, and constant $c_1$c1​.
2. Equation 2 Coefficients – $a_2$a2​, $b_2$b2​, and constant $c_2$c2​.

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 $x$x and $y$y.
• 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:$$2x + 3y = 16$$2x+3y=16 $$4x – y = 10$$4x−y=10

Step 1: Eliminate y

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

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

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

Step 3: Solve for y

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

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