Question

if 2a-3b=0,finda-b/a+b​

Answer 1

Answer:

2a=3b

a/b=3/2

by applying componendo and dividendo rule

a+b/a-b=3+2/3-2

a+b/a-b=5/1

after rationalizing

a-b/a+b=1/5

Answer 2

Answer:

2a-3b = 0

a-b\a+b. ........(1)

Step-by-step explanation:

2a-3b=0

2a = 3b.

a = 3b/2 ........(2)

Puttin eq(2) in (1)

=(3b/2 - b) \ (3b/2+b)

=(3b-2b/2) \ (3b+2b/2)

=(b/2) \ (5b/2)

=b/2 x 2/5b

= 1/5

Therefore

a - b\a+b = 1/5
