Pair Of Linear Equations In Two Variables
On comparing the ratios, find out whether the lines representing the following pairs of linear equations at a point, are parallel or coincident:
(i) 5x − 4y + 8 = 0
7x + 6y − 9 = 0
Comparing these equations with
and , we obtain
Hence, the lines representing the given pair of equations have a unique solution and the pair of lines intersects at exactly one point.
(ii) 9x +...
