Question

If a+b / a-b = 4/3 then a/b = ?​

Answer 1

Answer:

Given: a+b/a-b=4/3

by elimination method

a+b=4------1

a-b=3-------2

2a=1

a=1/2

putting a=1/2 in eq 1

1/2 + b =4

b=4*2/1

=8/1

Answer 2

Answer:

(a+b)/(a-b)=4/3

by cross multiplication:

3a+3b=4a-4b

0=4a-3a-4b-3b

0=a-7b

a=7b

a/b=7
