Question

2a+b/a+4b=3 then a+b/a+2b=?
​

Answer 1

Answer:

2a+b=3(a+4b) 2a+b=3a+12b 2a-3a=12b-b

2a+b=3(a+4b) 2a+b=3a+12b 2a-3a=12b-b- a = 11b => a = - 11b.

2a+b=3(a+4b) 2a+b=3a+12b 2a-3a=12b-b- a = 11b => a = - 11b.(a + b)(a + 2b) = (- 11b + b)/(- 11b + 2b).

2a+b=3(a+4b) 2a+b=3a+12b 2a-3a=12b-b- a = 11b => a = - 11b.(a + b)(a + 2b) = (- 11b + b)/(- 11b + 2b).= - 10b/- 9b = 10/9.

2a+b=3(a+4b) 2a+b=3a+12b 2a-3a=12b-b- a = 11b => a = - 11b.(a + b)(a + 2b) = (- 11b + b)/(- 11b + 2b).= - 10b/- 9b = 10/9.(a + b)/(a + 2b) = 10/9.
