4x+5/(3x+11)=13/17
cross multiply
17(4x+5)=13(3x+11)
68x+85=39x+143
68x-39x=143-85
29x=58
x=2

Hi ,
If a : b = c : d then
ad = bc
Now ,
( 4x + 5 ) : ( 3x + 11 ) = 13 : 17
( 4x + 5 ) × 17 = ( 3x + 11 ) × 13
68x + 85 = 39x + 143
68x - 39x = 143 - 85
29x = 58
x = 58 / 29
x = 2
I hope this helps you.
:)
