Question

the pair of equation X + 2 Y is equal to 7 and 3 X + B Y is equal to 16 represent Parallel Lines if​

Answer 1

Answer:

Step-by-step explanation:

px + qy = r  .....1

tx + uy = v  .....2

1 , 2 are parallel if

p/t = q/y

here given

x + 2y = 7

and

3x + by = 16

=> 1/3 = 2/b

=> b = 6

Hope it helps
