Linear Equations

This video helps students to find answer to following questions:

• What is an equation?

• Why do we need equations?

• How do we frame equations?

• What is means by solution of an equation?

• How do we solve equations

This video helps students to:

• Plot two simultaneous equations in the same graph.

• Identify the nature of solution from the graph.

• Find the solution if it is unique.

• Shade/identify the area bound by the lines/axes.

This video helps students to:

• Find the ratios of coefficients.

• Compare the ratios to find the nature of solutions

• Find the missing constant when nature of solution is given.

This video helps students to:

• Find the solution of two simultaneous equation using the method of substitution.

This video helps students to:

• Find the solution of two simultaneous equation using the method of elimination (Eliminating the Coefficients).

This video helps students to:

• Find the solution of two simultaneous equation using the method of cross multiplication.

This video helps students to:

• Understand the derivation and the logic behind the cross multiplication method

This video helps students to:

• Find the solution of equations where the coefficients of X and Y are exchanged in both equations.

This video helps students to:

• Find the solution of equations which are reduced to linear form (by substitution) and then solved.

This video helps students to:

• Apply the substitution method to solve linear equations of 3 variables.

• Solve the linear equations which have coefficients as the variables (arbitrary constants)
