we have to the equation

a linear equation is an equation which is graphed as a line. An example would be 2X+4=10. We want to isolate x, If we do the same thing to both sides of an equation, both sides still remain equal , so the first thing we do is subtract 4 from both sides, and we get 2x=6. Then divide both sides by 2 and x =3.

None of the above really hit the spot. A linear equation is an equation where the highest power of any variable involved is 1. These equations can have any number of variables. They always equal something.
Examples:
5x = 20
x + y = 20
x + 2y - 3z = 100
z - x = 100(y + w - 2)
Equations with two variables can have infinite solutions, as both the variables can assume any value depending on what they equal. To get their exact value, you need another equation with the same values of the two variables. These equations are called simultaneous equations.
Example:
x + y = 90
2x = 100-3y
Equations with three variables need three equations, four need four equations and so on.
what we have to do in linear equation?
We have to find the value of each variable concerned or graph the equation.

Linear Equation is a Equation which has degree of ONE ....
it may have N number variables .
To find the values of N variables v should have N number of equations .
For EX for two variable linear equation, V need TWO linear equations to find the values of the variables

The first degree equation is called a linear equation. We have to separate the unknown quantity to one side of the equation and the remaining other side.
By simplifying we get the value of unknown quantity.

linear equations are used to find one unknown quantity.
It can be drawn like a straight line also because it is in the form of y=mx+c. it is an equation to draw a line. for more challenging problems go to www.mathsindia.com

it is an equation in the form "ax + by + c = 0" where x and y are 2 variables. e.g. 2x + y = 3
x + y = 3

THE BASIC THING WHICH WE HAVE TO DO IN LINEAR EQUATIONS IS TO GET THE VARIABLES IN ONE SIDE AND THE CONSTANTS AT THE OTHER.AND THEN SOLVE THE BOTH SIDES FOR EG. 2B+55=100+B
2B-B=100-55
B=45

U MUST IF U HAVE 4 coordinates u have to make like y1-y2dividex1-x2 then u will get the slope then u must make y=mx+c m is the slope u must get c if y=2 m=4 then 4=2x+c 2x=-4 problem solved..........

we have to transfer the constantsfrom rhs to lhs&vice versa like
2x+3=5
=>2x=5-3
=>x=2/2
so, x=1
