D. 2

Answer 1

`\\ \sf\longmapsto (AK)/(DK)=(CK)/(BK)`

`\\ \sf\longmapsto (14)/(12)=(4x+1)/(3x+3)`

`\\ \sf\longmapsto (7)/(6)=(4x+1)/(3x+3)`

`\\ \sf\longmapsto 7(3x+3)=6(4x+1)`

`\\ \sf\longmapsto 21x+21=24x+6`

`\\ \sf\longmapsto 24x-21x=21-6`

`\\ \sf\longmapsto 3x=15`

`\\ \sf\longmapsto x=(15)/(3)`

`\\ \sf\longmapsto x=5`
