Pair Of Linear Equations In Two Variables

Question 3:

On comparing the ratios, find out whether the following pair of linear equations are consistent, or inconsistent.

Answer:

(i) 3x + 2y = 5

2x − 3y = 7

These linear equations are intersecting each other at one point and thus have only one possible solution. Hence, the pair of linear equations is consistent.

(ii)2x − 3y = 8

4x − 6y = 9

Since ,

Therefore, these linear equations are parallel to each other and t...
