Question

2. If 2x – 3y = 8; 4x + 6y = 7, then pair of equations has Unique solutions. is it true

class 10th pls answer fast if u know. its urgent ​

Answer 1

Answer:

yes it is true

Step-by-step explanation:

a1 = 2, b1= -3 , C1= -8

A2=4, b2= 6 , C2 = -7

a1/b1 = 2/4 = 1/2

A2/b2 = -3/6 = -1/2

since a1/b1 is not equal to A2/b2

therefore it is true . The pair of equations have a unique solution
