If a/b x - 1 = b/a x - 3 , then the value of x is:

1.

If 1-sym-oparen-h1 ax - 1=bx - 3, then the value of x is:ba

[A].	1/2
[B].	1
[C].	2
[D].	7/2

Answer: Option C

Explanation:

Given	a		x - 1	=		b		x - 3
	b					a

1-sym-oparen-h1

a

1-sym-cparen-h1

x - 1

=

1-sym-oparen-h1

a

1-sym-cparen-h1

-(x - 3)

=

1-sym-oparen-h1

a

1-sym-cparen-h1

(3 - x)

b

b

b

x - 1 = 3 - x

2x = 4

x = 2.
