Explain how to apply elimination in solving a system of equations.?

Set up both equations by multiplication or division in such a way that when the two are added together one variable is eliminated. Solve fot the other variable then use one of the original equations to solve for the other variable.

To solve a system of linear equation by elimination process

1)Bring the co-efficient of any one variable to the same .

2) If the signs of both variable are same (having the same co-efficients)

then subtract the two eq's.

3)If the signs are different then add the two eq'ns so that like terms get eliminated.

4)The value of one variable is calculated

5)By subtituting the value of known variable unknown variable can be

found.
