CBSE Class 10 Maths Graphical method of solution of a pair of linear equation
|
Let x is at the unit place and y is at ten's place, so 10x+y+27=10y+x
Compare the ratios of coefficients of x, y and constant term.
• Case 1 - If the lines intersect at a point, then the given system has a unique solution given by the coordinates of the point of intersection.
• Case 2 - If the lines are coincident, then the system is consistent and has infinitely many solutions. In this case, every solution of one of the equations is a solution of the system.
• Case 3 - If the lines are parallel, then the given system of equations is inconsistent i.e., it has no solution.
Solve graphically the system of linear equations
Solve both the equations together.
Recall consistent and inconsistent systems of linear equations
Let one number be x,and another be y, and solve the so formed equations.
Solve graphically the system of linear equations
consistent & inconsistent solution
Solve using determinant and then it's equal to zero.
