Answer 2

Answer:

a = - 3/2

b = - 1

Step-by-step explanation:

6/a = 7/b + 3

1/2a = 1/3b

Let 1/a be x and 1/b be y

6 x = 7 y + 3 .........( 1 )

x/2 = y/3

⇒ 3 x = 2 y

⇒ 6 x = 4 y

Put this in 1 :

4 y = 7 y + 3

⇒ - 3 y = 3

⇒ y = 3/-3 = - 1

⇒ 1/b = - 1

⇒ b = - 1

6/a = - 7 + 3

⇒ 6/a = - 4

⇒ 1/a = - 4/6

⇒ 1/a = -2/3

⇒ a = -3/2
