The value of m for which lines 14x + my = 20 and -3x + 2y = 16 are parallel, is :
The pair of linear equations 5x + 4y = 20 and 10x + 8y = 16 has :
The value of k for which the system of linear equations x + 2y = 3, 5x + ky + 7 = 0 is inconsistent is:
Is the pair of linear equation consistent / inconsistent? If consistent, obtain the solution graphically: 2x – 2y – 2 = 0 ; 4x – 4y – 5 = 0
Find out whether the following pair of linear equations are consistent or inconsistent : 5x − 3y = 11, −10x + 6y = 22
