CLASS 10, PAIR OF LINEAR EQUATIONS IN TWO VARIABLES, EXERCISE 3.1 (3rd Main Problems Solved)

3. On comparing the ratios a1/a2 , b1/b2 , c1/c2 , find out whether the following pair of linear equations are consistent, or inconsistent.
(i) 3x + 2y = 5 ; 2x − 3y = 7
(ii) 2x − 3y = 8 ; 4x − 6y = 9
(iii) 3/2 x + 5/3 y = 7 ; 9x − 10y = 14
(iv) 5x − 3y = 11 ; −10x + 6y = −22
(v) 4/3 x + 2y = 8 ; 2x + 3y = 12
