How to Solve Simultaneous Equations Online

Simultaneous equations are two or more equations with multiple variables. A solution of those equations is a set of variables that simultaneously satisfy all equations. Obtaining such a solution is a tedious and error-prone process if done by hand. Available online resources allow you to instantly obtain a solution for two simultaneous linear equations.
Linear equations can written in the standard form as
a1X+b1Y=c1; a2X +b2Y=c2. Abbreviation: a1,a2,b1,b2,c1 and c2 are known coefficients in equations, and "X" and "Y" are variables.
As an example, obtain the solution for the equations 5X-7Y=31 and -4X+3Y=-17.

Instructions

1. Open the web browser and navigate to the equation solver webpage at hellam.net/algebra/simul1.html.

2. Enter the first equation's coefficients ("a1", "b1" and "c1") in the first row of boxes from left to right.
   In our example, it would be numbers 5, -7 and 31.

3. Enter the second equation's coefficients ("a2", "b2" and "c2") in the second row of boxes from left to right.
   In our example, it would be numbers -4, 3 and -17.

4. Click the button "Solve it, " and read the solution in the boxes next to "x=" and "y=."
   In our example, you would get "x=2" and "y=-3." Note: you may need to round results.
