Introduction to online simultaneous Equation:
A set of linear equations having a common solution set is called a system of simultaneous linear equation. In solving simultaneous equation section we are going to learn how to solve the linear equations in three variables To find the values of three unknowns, we need to be given three linear equations on three unknown variables.In general online is defined as tutoring on internet. Thus the solving of simultaneous equation which is taught on internet is known as solving online simultaneous equation.
Having problem with list of algebra formulas keep reading my upcoming posts, i will try to help you.
Procedure for solving three given linear equations with three variables x, y, z
Three equations are given.
Take any two, say the first two equations.
Eliminate one variable say z.
Similarly eliminate z from the second and the third (or first and the third equation).
We get two linear equations in x, y.
Solve them in the usual way learnt in early cases.
Substitute the values of x and y in any one of the three equations to get the value of z.
Thus the values of x, y and z are obtained.

Example Problems on online simultaneous equation:
Example 1: Solve : x+ y = 3, y + z = –5, z + x = 2.
Solution: Let the equations be identified as
x + y = 3------------------- (1)
y + z = –5 ------------------(2)
z + x = 2 --------------------(3)
Adding all the three equations, we get
2x + 2y + 2z = 3 + (–5) + 2 or 2(x + y + z) = 0 or x + y + z = 0 (4)
Substituting y + z = –5 in equation (4) we get x + (–5) = 0 ∴x = 5.
Substituting z + x = 2 in equation (4) we get y + 2 = 0 ∴ y = –2.
Substituting x = 5 in equation (3) we get z + 5 = 2 or z = 2–5 = –3
The solution is x = 5, y = –2, z = –3.
Example 2: solve: x +3y = 4, x + 6y = 2.
Solution: Let the equation can be written as
X + 3y = 4 ------------(1)
X + 6y = 2 ------------(2)
Changing the sign __-__-____-___
-3y = 2
Y = -(2/3).
Sub y in (1) we get
X + 3{-(2/3)} = 4
X – 2 = 4
X = 6.
