Specific Objective of this video:

Algebraic Methods of Solving a Pair of Linear Equations

• Solving the pair of linear equations by elimination method and Substitution Method.

Description: This video is designed to solve the pair of linear equations by elimination method.

Students will make the coefficient of one variable equal in both the equations by multiplying

both equations will suitable numbers. They will add/subtract the equations so that term having

same variable eliminates. Further they will solve the linear equation in one variable which they

will get and find the value of that variable. They will get the value of another variable and write the solution of pair of linear equations.

Execution:

Make the coefficients of any one variable equal in both the equations.

Add/subtract the equations to eliminate one variable.

Solve the equation thus obtained and get the value of one variable.

Find the value of second variable by using the value of first variable.

Write the solution of pair of linear equation.

00:02 Q1. Solve the following pair of linear equations by the elimination method and the substitution method :
